Prepared Remarks:
Operator
Good afternoon, my name is Doug and I'll be your conference operator today. At this time, I'd like to welcome everyone to the KLA Corporation March quarter 2024 earnings conference call and webcast. All participant lines have been placed on a listen-only mode to prevent any background noise. [Operator instructions] Thank you.
I will now turn the call over to Kevin Kessel, vice president of investor relations and market analytics. Please go ahead.
Kevin Kessel -- Vice President of Investor Relations and Market Analytics
Thank you for joining our earnings call to discuss the March 2024 results in the June quarter outlook. I am joined by our CEO Rick Wallace and our CFO Bren Higgins. We will discuss today's results released after the market close and available on our IR website along with the supplemental materials. Today's discussion and metrics are presented on a non-GAAP financial basis unless otherwise specified.
All four-year references are to calendar years. Earnings materials contain a detailed reconciliation of GAAP to non-GAAP results. KLA's IR website also contains future investor events, presentations, corporate governance information, and links to the SEC filings, including our most recent annual report and quarterly reports on Forms 10-K and 10-Q. Our comments today are subject to risks and uncertainties reflected in the disclosures of risk factors in our SEC filings.
Any forward-looking statements, including those we make on the call today, are subject to those risks, and KLA cannot guarantee those forward-looking statements will come true. Our actual results may differ significantly from those projected in our forward-looking statements. Rick will begin the call with some introductory comments, followed by Brent with additional financial highlights, including our outlook. We'll now turn the call over to our CEO, Rick Wallace.
Rick?
Rick Wallace -- Chief Executive Officer
Thank you, Kevin. Today I will review KLA's March quarter results and highlights and address the new market share reports, as well as a broader industry outlook. KLA's revenue of $2.36 billion was above the midpoint of our guidance range. EPS results, both non-GAAP and GAAP, were above the midpoint of the adjusted guidance we provided on March 18th, in conjunction with the decision to exit the flat panel business.
Market conditions have stabilized, and we expect our business to improve as we progress through the year. We're encouraged by the improvement in our customers' business across multiple end markets, which is driving discussions with our customers about future opportunities for leading-edge capacity investments. At the start of each year, new global market share reports are published by third parties that provide additional insights into the state of our industry. These reports show consistent, long-term KLA market leadership and process control, and demonstrate the strength of our diverse portfolio that offers our customers unique capabilities to address their technology challenges while meeting their productivity demands.
This year, following significant gains in 2022, KLA's 2023 market share declined by nearly 1%, driven primarily by a loss in access to approximately 10% of the China market as a result of US government export controls. That said, KLA's consistent market leadership and process control, and some of the most critical markets in WFE, reflect the success of our customer-focused strategies and the power of our portfolio. We're confident that KLA's quarterly revenues bottomed in the March quarter, as expressed in our prior earnings call. In foundry/logic, simultaneous investments across multiple nodes and slowly rising capital intensity continue to be a long-term tailwind.
Additionally, the increasing complexity in advanced packaging applications for AI and other advanced technologies drives demand for both our process tool and process control products. Overall demand growth, along with increasing technology requirements, will drive the need for more capability from inspection and metrology systems. Our advanced packaging business will generate approximately $400 million in run rate in 2024, and we expect this business to achieve growth rates meaningfully above the growth rate of WFE going forward. In services, our business grew to $590 million in the quarter, up 4% sequentially and 12% year over year.
Quarterly free cash flow was $838 million, and the last 12-month free cash flow was $3.1 billion, with a free cash flow margin of 32% over the period. KLA's quarterly results continue to demonstrate our sustained process control leadership and the success of our broad portfolio and product strategies. Customers continue to prioritize and invest in leading-edge technology transition, and this aligns with KLA's highest-value product offerings. In this industry environment, KLA will continue to focus on supporting customer requirements, executing on product roadmaps, and preparing for growth at the leading edge.
Bren will now discuss the financials and our outlook further.
Bren Higgins -- Chief Financial Officer
Thank you, Rick. KLA's quarterly results demonstrated a consistent execution of our global team. Despite the challenges and complexity of the current industry environment, KLA continues to show resourcefulness and the ability to adapt to meeting customers' changing requirements. Quarterly revenue was $2.36 billion, above the guidance midpoint of $2.3 billion.
Non-GAAP diluted EPS was $5.26, above the guidance midpoint of $4.83. GAAP diluted EPS was $4.43, above the guidance midpoint of $4.06. In the March quarter, both non-GAAP and GAAP diluted EPS were negatively impacted by a $62 million charge for excess and obsolete inventory related to the company's strategic decision to exit the flat panel display business announced on March 18. This charge had a $0.40 impact on EPS.
Excluding this item, diluted non-GAAP EPS would have been $5.66. Non-GAAP gross margin was 59.8%, above the top end of the revised guidance range. Excluding the FPD charge, non-GAAP gross margin would have been 62.4%, and roughly flat sequentially. Non-GAAP operating expenses were flat sequentially at $544 million, comprised of $320 million in R&D and $224 million in SG&A.
Non-GAAP EPS at the 13.5% guided tax rate would have been $0.04 higher, or $5.30. Non-GAAP operating margin was 36.8%, non-GAAP other income and expense net was a $34 million expense, and the quarterly non-GAAP effective tax rate was 14.2%. Quarterly non-GAAP net income was $715 million, GAAP net income was $602 million, cash flow from operations was $910 million, and free cash flow was $838 million. The breakdown of revenue by reportable segments and markets and major products and regions can be found within the shareholder letter and slides.
Turning to the balance sheet, KLA ended the quarter with $4.3 billion in total cash, cash equivalents, and marketable securities, debt of $6.7 billion, and a flexible and attractive bond maturity profile, supported by strong investment grade ratings from all three agencies. On February 1st, KLA issued $500 million of 4.7% senior notes due in 2034 and $250 million of 4.95% senior notes due in 2052. The company expects to use the net proceeds from the notes operating for general corporate purposes, including the repayment of outstanding indebtedness at or prior to maturity. Moving to our outlook, we remain encouraged by constructive customer discussions around their future investment plans, which are further supported by recent reports of an improving end-market demand environment and customer profitability.
Consistent with these industry trends, as we indicated last quarter, we believe our business bottomed from a revenue perspective in the March quarter, and looking ahead through the balance of calendar 2024, growth is resuming in the June quarter, and we expect business levels to improve as we progress through the year. For calendar 2024, our high-level outlook remains unchanged. We still expect WFE demand to be roughly flat to modestly up from 2023, and that the second half of the calendar year will be stronger than the first half. KLA's June quarter guidance is as follows.
Revenue of $2.5 billion, plus or minus $125 million. Foundry logic revenue from semiconductor customers is forecasted to be approximately 82%, and memory is expected to be 18% of semi-process control systems revenue. Within memory, DRAM is expected to be about 78% of the segment mix, and NAND the remaining 22%. Non-GAAP gross margin is forecasted to be in a range of 61.5%, plus or minus one percentage point based on product mix expectations.
For calendar 2024, based on current industry outlook, top-line growth expectations, higher forecasted growth in services, and expected systems product mix, we are modeling non-GAAP gross margins to be relatively stable around the mid-61% range. Variability quarter to quarter is typically driven by product mix fluctuations. Non-GAAP operating expenses are forecasted in the June quarter to be approximately $550 million, as our merit adjustment process occurred in the March quarter. Looking ahead, we continue to expect $5 million to $10 million incremental growth in quarterly operating expenses for the remainder of calendar 2024, supported by expected revenue growth.
Other model assumptions for the June quarter include non-GAAP other income and expense net of approximately a $38 million expense. GAAP diluted EPS is expected to be $5.66, plus or minus $0.60, and non-GAAP diluted EPS of $6.07, plus or minus $0.60. EPS guidance is based on a fully diluted share count of approximately 135.4 million shares. In conclusion, as we articulated 12 weeks ago, we are encouraged with the indicators and improvement ranging from our customers' conversations to the public reports over the past few months.
KLA remains focused on delivering a differentiated product portfolio that anticipates customers' technology roadmap requirements and drives our longer-term growth expectations. With the KLA operating model guiding best-in-class execution, KLA continues to implement strategic objectives which are geared to drive outperformance. With a focus on customer success, delivering innovative and differentiated solutions, and operational excellence, KLA is able to deliver industry-leading financial and free cash flow performance and return capital consistently. The past few years have solidified our confidence in the increasing importance of process control and enabling technology advancements and optimizing yield across a high semiconductor device design mix volume production environment.
This bodes well for KLA's long-term growth outlook as near-term industry demand trends are continuing to improve. In alignment with this, KLA's business is improving, and the long-term secular trends driving semiconductor industry demand and investments in WFE remain intact in both legacy and leading-edge markets. That concludes the prepared remarks. Kevin, let's begin the Q&A.
Kevin Kessel -- Vice President of Investor Relations and Market Analytics
Thank you, Bren. Operator, can you please provide instructions for polling?
Questions & Answers:
Operator
Absolutely. [Operator instructions] In the interest of time, we also ask that you please limit yourself to one question and one follow-up. We'll now take our first question from Harlan Sur with J.P. Morgan.
Please go ahead. Your line is open.
Harlan Sur -- J.P. Morgan -- Analyst
Good afternoon. Thanks for taking my question. Last year and first half of this year was more mature node by spending maybe more infrastructure focused as well. As you step into the second half of this year, it does feel like advanced momentum is starting to accelerate, rate, both foundry and logic and memory, and appears to be reflected in your confidence on improving spending outlook for this calendar year.
Given your relatively longer lead time, your critical role in enabling these advanced technology migrations. Like how are customer discussions the initial forecast visibility and outlook for calendar 2025 shaping up for the team. I mean, I assume it's a more advanced technology-driven profile next year, which should be good for the team, but wanted to get your views.
Rick Wallace -- Chief Executive Officer
Great, Harlan. Thanks for the question, this is Rick. Absolutely, we are having different kind of discussions now than we've had for a while with our leading-edge logic and memory customers. As they prepare for the ramp and we're seeing increased demand for, they are seeing increased demand, they're talking about tool availability, scheduling of resources, making sure that they don't get behind, really conversations we haven't had for a while.
I think the build-outs are still as we indicated, we see kind of stability with rising demand through the year, but the real build-out is going to come in 2025 and beyond that as we see some of the conversations we're having. So, really good indicators, leading indicators, design starts, advanced node discussions, R&D work. So, we feel pretty good about the setup.
Harlan Sur -- J.P. Morgan -- Analyst
Great. Thanks for that. And did you see the continued growth in the services business with industry utilization is clearly on an upward trajectory. You've got record number of tools coming off warranty customers, I think, wanting more value-added services and offerings just given the complexity challenges ahead.
Has the view on the services growth profile improved relative to the last earnings call? I know you talked about being at the upper end of that sort of 12% to 14% sort of target range this year on the last call. Has that changed?
Bren Higgins -- Chief Financial Officer
I would say hey Harlan, it's Bren. I would say, look, we're continuing to see very strong momentum utilization rates are improving. We had a lot of tools come off of warranty, and they go into contract and our conversion rate is about 95%. So, that's very positive.
Customers are extending lives of the systems, which bodes well for long-term service growth overall. So, I think as we track here, I think we feel pretty good about the range that we have, and we're closer to the upper end for sure than the lower end as we move forward over the next few years.
Harlan Sur -- J.P. Morgan -- Analyst
Thank you.
Operator
We'll take our next question from C.J. Muse with Cantor Fitzgerald. Please go ahead. Your line is open.
C.J. Muse -- Cantor Fitzgerald -- Analyst
Good afternoon, thanks for taking the question. I guess first question, a near-term question on the mix you expect for June, which a pretty massive shift to foundry/logic from memory. So, I guess as part of that, can you speak to some of the underlying drivers? And within that, do you see perhaps a pickup from domestic China memory beyond the June quarter? Or I think in the prior quarter, you talked about revenue rec pushed to the June quarter. So, curious about the moving parts there.
Bren Higgins -- Chief Financial Officer
Yeah. I would say as far as China memory goes, it's more first half heavy than second half, while we're having very positive conversations with our customers on the memory front, as Rick indicated, in terms of long-term plans, we're seeing their businesses now improve. We're seeing profitability and cash flow starting to improve. But we don't expect any significant investments as we move through the rest of the year.
Nothing could change. But I think that the profile, it might tick up a little bit in the second half overall, non-China but I don't see it changing in a real meaningful way. If you look back at our business, we were a little bit over 70%, maybe logic/foundry in 2023. And I think we're going to be right around 70%.
I think it's going to be a pretty similar overall mix this year.
C.J. Muse -- Cantor Fitzgerald -- Analyst
Excellent. And then in terms of your commentary around accelerating top-line revenues throughout the remainder of calendar 2024. I guess can you speak to the main drivers there as it relates to perhaps two-nanometer pilot, logic in Arizona, handset-related EPC. What's really driving that? And is there sort of a percentage growth rate we should be thinking about half on half? Thanks so much.
Bren Higgins -- Chief Financial Officer
Yes. CJ, I think you covered most of them, right? We will see some early investment in two-nanometer. You have the three-nanometer build-out. You have the investment that you mentioned in Arizona.
So, those are all pretty good for the logic/foundry segment. Right now, when I look at the overall business first half versus second half, I think the second half is high single digits versus the first half in that ballpark. We're not guiding, but I think it's going to end up in that range as we progress through the year. On the EPC front, I think it is a little bit stronger.
You do have some seasonality in EPC in the first part of the year. But we'll see some improvement there, I think, as we move through the second half of the year as well.
Rick Wallace -- Chief Executive Officer
And of course, service is growing quarter on quarter. So, you've got that effect as well.
Operator
And we'll take our next question from Krish Sankar with TD Cowen. Please go ahead. Your line is open.
Krish Sankar -- TD Cowen -- Analyst
Yes, thanks for taking my questions. Two of them. One is Bren, last quarter you kind of said that for KLA, the overall calendar 2024 revenues could grow mid-single digits based on WFE. And obviously, some of these expectations WFE growth is going to be higher thanks to [indiscernible].
Given that you do have some exposure on that side. I'm just kind of curious how to think about your overall revenue profile for this year, year over year. And then I have a follow-up.
Bren Higgins -- Chief Financial Officer
Yes. And when you look at the WFE level, we talked about flat to modestly up. And that, I think, depends on your view of WFE as everybody adds it up differently. Our view is that WFE was probably $90 billion to $91 billion, and then it's slightly up from there or flat to slightly up from there in terms of how we're looking at this year.
So, I think that's the way to think about it. It simply put, given the WFE is more or less flat to modestly up, that we were going to see this increase in service that we've talked about. We're going to see some modest improvement in EPC. And we've seen some improvement given the outperformance we saw in March, the incremental guide into June in our semi-PC business.
So, I think overall, semi-EPC share in the overall market is probably going to be fairly consistent, maybe a little bit up from what we saw in 2023. And all that translates into our semi-EPC business roughly performing mostly in line with where we think the market is going to be for this year.
Krish Sankar -- TD Cowen -- Analyst
Got it. That's very helpful. And then a quick follow-up on China. Give you a long lead time, so I'm kind of curious how do you think about China.
You did say memory would be filtrated overall China revenues. And along the same path, if I back out the FPD gross margins from March to June is down 90 basis points QoQ. You said it's product mix? Is it mainly from China? I'm just kind of curious on this. Thank you.
Bren Higgins -- Chief Financial Officer
Yes. No, it's mostly product mix quarter on quarter, down from the FPD adjustment related to the inventory that we took related to the decision there. So, it's mostly just product mix across our semi-PC business. You do have some growth in service quarter on quarter and services is dilutive to the overall gross margin.
We believe it's accretive to the operating margin, but the gross margin is a little dilutive. And then the rest is just the normal product mix we have across the portfolio. Different margin profiles across the portfolio. And so, depending on what we're revenue in a given quarter, it can cause some fluctuation.
But I think the guidance range is appropriate, like we saw, I think we guided somewhere around 61.5% last quarter. It came in above 62%, depending on how things end up revenueing as we engage with customers and ship systems. There's always room for upside, which is why we give the range that we give. So, there's nothing really particular to actual customers.
It's more about the product mix of all regions. It's more about the product mix of the products we're shipping and getting acceptance on.
Krish Sankar -- TD Cowen -- Analyst
And then is China's fitment to the rest of the year, similar range or?
Bren Higgins -- Chief Financial Officer
So, China is interesting. I think it's probably flattish over the course of the year. Second half is more or less flattish with the first half. The mix is changing a bit in terms of the end market mix.
But we see it as a percent of the total coming down as we see most of the growth in the year coming from our non-China customers.
Krish Sankar -- TD Cowen -- Analyst
Thank you very much.
Operator
We'll take our next question from Brian Chin with Stifel. Please go ahead. Your line is open.
Brian Chin -- Stifel Financial Corp. -- Analyst
Hi, there. Thanks for letting us ask a few questions. I guess, is sort of asked earlier, but with all these CHIPS Act announcements continuing to roll in, has this solidified the timing or magnitude of any of the US greenfields to build out or maybe what is your latest thinking on some of these projects?
Rick Wallace -- Chief Executive Officer
Well, yeah, there have been many announcements, and it's exciting to see. But when you look at the timing for those projects, even, for example, the one that was announced today in New York, that one's quite a ways out. So, I think the approval of the funding relative to the timing, the customers we talk to, they're excited about this, the chance to reshore under the US, but they're still building their capacity based on market demand. So, it doesn't really affect the overall capacity investment.
They're gauging that based on the overall demand. And I think what happens is it's the size of the investment in terms of how many wafers start to go out at what point is driven by the market. So, we'd stick to the comments about when the, what we see for the business environment, relatively independent of what location that the customers are choosing to make those investments.
Brian Chin -- Stifel Financial Corp. -- Analyst
Got it. That's fair. And then maybe I did notice that in the shareholder letter and on the call, you highlighted advanced packaging revenue could be around $400 million in calendar 2024, what growth rate does that represent versus calendar 2023? And then how would you size your served addressable market in advanced packaging, which I know certainly cross is, I guess, boundaries across your portfolio?
Bren Higgins -- Chief Financial Officer
Yes, so it's greater than 25%. So, we're somewhere down in around 300 in 2023, a little over 300, and close to 400 expectation for 2024. It's across a broad portfolio, right? We have process control, which we sell to those customers, which is inspection metrology, but also process tools in our specialty semiconductor business. It's about 50-50 in terms of the contribution from each part of the portfolio.
And I think on the go forward, we feel pretty excited about the opportunity to see a growth rate that's meaningfully faster than WFE.
Rick Wallace -- Chief Executive Officer
Yeah, and I think for opportunity, there's a couple of factors that are in play. One is the speed with which customers are accelerating their packaging efforts, the degree with which those are requiring leading edge. Our ability to make it make sense from a business standpoint, the packaging challenges really need to be leading edge. So, there's still a number of packaging applications that are in markets that are served by lower-end competitors that we're not really competing for.
So, it has to do with how quickly the new technologies come on. But this has been an increased conversation in meetings that we've been having with leading customers for the last year or so. It was already talked about, but it's accelerating. So, I think it's hard to judge exactly what the growth rate will be at this point, but it's pretty clear that there's a huge demand.
And for many customers, they view it as the competitive necessity in order to, there's very much of a race of getting that new capability into the market, especially as it pertains to some of the AI applications. So, I would say that it's a huge driver for our customers. We're engaged. There's a lot of requests for new capability, and some of it comes down to us developing solutions in conjunction with those customers to meet those demands.
But on its own, as it stands right now, it will outgrow WFE, and we think it has the potential to go well beyond that, depending on how the adoption goes and how we continue to execute against it.
Brian Chin -- Stifel Financial Corp. -- Analyst
Great. Thanks for all the color.
Operator
We'll take our next question from Tim Arcuri with UBS. Please go ahead. Your line is open.
Tim Arcuri -- UBS -- Analyst
Thanks a lot. I wanted to ask about N2, Rick. So, there has been a lot of talk recently about the big volume for N2 is not going to be probably until 2026, although there will certainly be some customers, crypto customers, and what not, that will ramp in 2025. So, there will be capacity that gets installed next year.
So, I guess my question is, how much of a driver do you think N2 will specifically be for your business? Are you seeing any of that yet? Is it more of a back-happening this year thing? I'm just asking about timing, when that starts to help your business.
Rick Wallace -- Chief Executive Officer
Yeah, great question. It is definitely being one of the conversations we're having with critical customers about timing, and we have seen part of our optimism going forward is those conversations are being pulled in in terms of the needs because our customers are feeling end market pull. So, I think you're right that the bulk of it, the highest volume, will be in 2026. But for KLA, we're already seeing those conversations, and we'll start to see some meaningful business in 2025 for that with orders coming toward the end of 2024, as customers figure it out.
The other thing is we're seeing a number of advanced design starts for the two-nanometer node. It's a big, as Tim, it's a big power-favorable node. And so, for a lot of customers, some of the challenges around data center and, frankly, around AI are power-related in terms of customers being able to even build those sites. So, it's a big driver for our customers right now.
So, we think N2 is going to be a very significant node, and we're going to definitely see a lot of that. We're already seeing the activity, but it'll be a big factor in 2025 and then as we go through 2025.
Tim Arcuri -- UBS -- Analyst
Got it. Got it. OK, perfect. And then I want to ask about China.
Bren, you just said, I think you said China is going to be flattest, shorter than the back half of the year. I mean, it sounds like every quarter China keeps getting stronger, and I think it's going to down-tick, and it doesn't because they're just going to take tools as long as they're allowed to take tools. So, my question is really just on the mix around China. Is the back half filling in a bit because of new customers? I mean, there's probably 30 or 40 new hubs being built, if not more than that, that are part of these compilations just under different names.
And so, is it these new, newly named fabs that are coming on that are sort of filling in the back half of the year? And then if, we've seen a lot of headlines around potential entity list additions, if this happens, which there's been a lot of headlines about it, but if it does happen, is this downside to what you're thinking for the back half of the year or for next year? Thanks.
Bren Higgins -- Chief Financial Officer
Well, Tim, I don't want to speculate about hypotheticals about what might come or not come from the US government in regards to further export controls, and we're continuing to work very closely with the government and spend a lot of time and resources to make sure that whatever the rules are that we're compliant. It's a pretty decent mix. I talked about DRAM being down. I think the wafer infrastructure in the second half, I think the wafer infrastructure is probably down a little bit in the second half.
I think the reticle infrastructure is probably up, and then the logic/foundry is up overall. And then when you net it all out, it's basically a flattish profile. The customer mix, you do have a number of new projects continuing to take systems, but you also have the, I'll call them the more mature legacy customers in China that are also part of that mix. So, I think, it's continuing to be healthy, I think, through this year.
And I think the profile as we, even beyond this year, feels like, kind of continues more or less at current levels. Obviously, those are like half to half. I mean, in any given quarter, we'll see some movement, but that's how we see things today.
Tim Arcuri -- UBS -- Analyst
OK. Awesome, thank you Bren.
Operator
We'll take our next question from c with Needham. Please go ahead. Your line is open.
Charles Shi -- Needham and Company -- Analyst
Thanks. I want to ask a question to build on what was discussed with the team earlier. So, TSMC definitely said that the revenue is going to ramp in 2026 for N2. And you kind of alluded to that, that you think the 2026 volume for you will be higher than 2025.
But if I look at how the 30-nanometer ramp look like? And it occurs to me that 2022, which was one year in terms of production timeline for the three-nanometer was a higher volume for you guys compared with probably 2023. So, I just really wonder about the fact that you said you think that 2026 will be a high volume for you compared with 2025. Was that coming from some discussion with the customers? And what's changed this time, why they want the kind of I mean, move the capacity to a little bit closer to the high volume at the point of entry to the high-volume production? Thanks.
Rick Wallace -- Chief Executive Officer
Yes, it's a great question. And there's a couple of things to consider when thinking about N2. First of all, this is now very clear in our customers' minds a race for AI capability. And so, you see several designs start happening, not just the ones we're most familiar with, but other players, too, designing for capability.
So, you have a very different demand environment. You also have a constrained capacity environment, now constrained somewhat even by the ability to build facilities. But the last factor is you have the KLA phenomenon is we get pulled in early. So, we're front-end loaded into some of these facilities because you need our systems to be able to qualify the rest.
So, it is a different node than what we've seen in quite a while because of those factors. And as we meet with customers, they are very concerned about supporting the demand that they're seeing. That's why we believe we're going to get a lot of pressure to support the end of this calendar year to start supporting some of the POs that we're going to see as they plan out those nodes. And it will go through, and we're talking about volume in 2026 for them, but toward the end of 2025 is when we'll be seeing more and more of that business.
And, of course, we don't know how much broader it's going to get in terms of the number of design starts. It is remarkable that there are this many designs specifically for one application at this point in the process. But it's pretty remarkably consistent as we talk to different customers and even their customers.
Charles Shi -- Needham and Company -- Analyst
Thanks for the color. Maybe a second question I want to ask you about the advanced packaging capability you're building there. It sounds like you're having more of the constructive conversation with your customers, maybe to put more KLA, more advanced process control capabilities into the packaging side of the process control. So, I get the overall idea, but I just really hope for you to provide a little bit more color.
What kind of areas do you think the customers are facing challenges in terms of maybe wrapping up COAs, maybe wrapping up SOIC, and where do you see, from a process control perspective, the biggest opportunities for KLA? Thanks.
Rick Wallace -- Chief Executive Officer
Yes, I'll give you some color just from two stories. One, years ago when we bought ICOS, part of the theory of that case was it was giving us exposure to the back end. And I remember meeting with one of our big customers and their back-end people, and they literally said to me, why are you guys talking to us about the back-end? That's not a KLA market. And fast forward to the end of last year, calendar year, in a meeting that Ahmad and I had with a critical customer, they had two topics they wanted to talk about.
One was our support of EUV and the ramping of continuous ramping of EUV designs and capabilities, and the other was advanced packaging. And these were the folks that were historically and traditionally responsible for the front end. And one of the things they said is we think you guys have the capability in a lot of your front-end tools, but we need that modified, and we need that for the back end, because the back end is a critical part of our differentiation, and that's the part that we need you to work with us to take what you consider front end tools and make it. And what we're more concerned with than cost, and this is often the case at the beginning of a node, they're more concerned with capability than they were necessarily on cost.
So, the dynamic has shifted pretty considerably. And again, I go to one of the biggest drivers for all this is all the work that's going on with AI, and if you look at the success and the requirement to have advanced packaging as part of those solutions, that's what's driving it. So, we kind of anticipated a few years ago that more and more trend was going to become more and more relevant, but we're seeing it very specifically with customers bringing front-end people that they've worked in the front end, having them work on these back-end challenges, and asking specifically for capability that we have in the front end to be used in the back end. And in some cases, we've done that with some of our inspection tools and capability.
But as you know, we have to make modifications to handling and some of the operating conditions to make that work. So, we're definitely seeing that, and in some cases, our ability to support and modify those systems will be the gating item for us to realize revenue on it, not the demand. The demand is there, and from a competitive standpoint, we're uniquely positioned to do that. So, we feel pretty good about the opportunity, and it's a major focus area for the company.

We'll take our next question from Chris Caso with Wolfe Research. Please go ahead. Your line is open.
Chris Caso -- Wolfe Research -- Analyst
Yeah, thank you. Good evening. Just a follow-up question with regards to memory. And I think I understand what you're saying with regard to this year, perhaps some improvement in non-China memory, but nothing significant.
I guess, what are your customers telling you to be prepared for perhaps as you're going into next year? We're starting to see some prices go up, utilization up. What's your expectations for the potential improvement in 2025?
Bren Higgins -- Chief Financial Officer
Yeah, Chris, you're seeing all the things you want to see, right? You're seeing pricing improve, customers are taking up utilization. Utilizations were very low. And so, there's a fair amount of capacity that's been out there. We're seeing the profitability improve and ultimately, that will translate into cash flow and then what we expect to be investment next year.
I think we're seeing more in DRAM driven by the leading edge of DRAM or expect to see more there. And then, of course, the drivers related to high bandwidth memory. But I think in some ways, it's the device market -- part of the market is improving this year, and that will translate into investment next year.
Chris Caso -- Wolfe Research -- Analyst
Got it. As a follow-up, with regard to service, I think last quarter, you talked about your expectation that being kind of the high end of a 12% to 14% target. Is that still the right way of thinking about it? Again, we've seen utilization rates improve here. Does that make that change your view of where services come out for the year?
Bren Higgins -- Chief Financial Officer
Well, it's certainly a factor in the growth that we're seeing this year. So, I've been pretty open that I thought that we'd be somewhere between 250 to 300 million of incremental service this year versus in 2023. I think we're closer to the top end of that range than the bottom. It is a factor, and given the nature of process control and the complexity of our systems, the mix, and the relatively lower volume, our customers tend to rely on us to ensure that they're optimizing their capital, particularly in environments when capital is constrained.
Yields matter a lot. And so, our utilizations never drop as much as process tools where they have more redundancy. But we are seeing it continue to improve, and so I think it's a good sign in terms of the overall market health and in our confidence about some of the growth drivers into next year.

We'll take our next question from Joe Quatrochi with Wells Fargo. Please go ahead. Your line is open.
Joe Quatrochi -- Wells Fargo Securities -- Analyst
Yes, thanks for taking the question. Wondering if you could comment, obviously, you seem pretty positive in terms of just the opportunity looking into next year and thinking about the size of N2 and recovery in the memory market, I guess, how does the conversation with your customers over the last several months and just thinking about your lead times to give you confidence in your ability to reach that 2026 target model?
Bren Higgins -- Chief Financial Officer
Well, I think our confidence is pretty good. We've made a lot of investments around the company in 2021 and 2022, both in terms of our own capacity, but also to ensure that our key suppliers have the capacity to support that kind of demand environment. So, it's one of the reasons why my inventory levels today are higher than -- and they continue to grow even where the market has corrected some because of the commitments we've made to ensure that the suppliers keep that capacity in place. So, we feel very good about our ability to leverage what we have.
I don't think we really have to make a lot of big investments to be able to support that trajectory. And I think we'll -- because of the investments, I think, frankly, they're a little bit of a headwind today in terms of the margins. So, I think over time, the leverage opportunity is also compelling if we see the kind of growth environment that we expect over the next couple of years.
Joe Quatrochi -- Wells Fargo Securities -- Analyst
OK. As a quick follow-up, Bren, I was wondering if you could give us RPO exiting the quarter.
Bren Higgins -- Chief Financial Officer
It wouldn't be a quarterly conference call without your question, Joe. So, $9.9-ish, we're going to file the Q in the morning or sometime tomorrow, I think. $9.9 billion, it was down about $750 million quarter on quarter. Deposits are about $677 million.
Joe Quatrochi -- Wells Fargo Securities -- Analyst
Perfect. Thank you.

We will take our next question from Tom O'Malley with Barclays. Please go ahead. Your line is open.
Tom O'Malley -- Barclays -- Analyst
Hey guys, thanks for taking the question. I think there's been a lot of discussion on the call about advanced packaging, and you guys have talked about how you had conversations already about potentially bringing some of your solutions from the front end to the back end. There's obviously some adjustments to those tools to get them ready. Can you talk about the timing of bringing those solutions there? Obviously, you're seeing a big growth rate in the back end.
But from the moment that you say, hey, we want to take a tool and address the back end to when you're actually selling that to a customer. Can you talk about how long that takes?
Rick Wallace -- Chief Executive Officer
Sure. And we had, yes, let's be clear. I mean we have some of our products already from the front end that are being used in the back end. That started a while ago.
We're just seeing an accelerated conversation about more tools where some customers will actually name specific tools that they want. So, it very much depends on the tool, and I can give you a range where it could be from three months, it could be a couple of years, depending on whether you're modifying something that's already being used in that kind of application and specializing it. So, it really depends, but I do think that we have some that are already there. So, part of our $400 million is from tools that were from the front end.
A fair amount of those, probably half of those, actually, and some are process capability from SPTS. So, it's really those are examples where we have it. And also, the case is some of those tools need to be upgraded to the later specifications as customers move forward in technology. So, that's why, you know, net-net, it's a positive, it's a growth segment for us.
We think it will continue to grow. Bren talked about the growth from last year, and it was a big driver for going back in time for the Orbotech acquisition was our belief that packaging opportunity was going to continue to grow. So, that's where we are on it. But it's very tool-specific how long it takes to modify.
Bren Higgins -- Chief Financial Officer
We also have new products that are going to support the substrate transition as the substrate integrates into the package. On the inspection side, as the lines and spaces shrink in the connecting layers, it will drive the need for more capability for more advanced inspection and metrology systems. And so, anytime you add sensitivity, you add capability, there tends to be a throughput or a volume hit. So, it creates an opportunity for us to sell, higher ASP systems that have more capability.
But if you're going to maintain the same sampling rate, then you'll need more systems. So, it's all a factor in terms of all these factors are all, positive in terms of how we think about the long-term opportunities.
Tom O'Malley -- Barclays -- Analyst
Super helpful. And then my second one is just kind of on the tidbits that you've given for the year. So, you said second half over first half, high single digits and you talked about kind of the mix of foundry/logic being similar to calendar year 2023, about that 70%. If you take those clues, you obviously see some really strong growth in memory in the second half.
Could you just help us with any color, obviously, March to June, your DRAM percentage went down a bit in terms of its contribution to memory? But in the second half, how should we be thinking about the DRAM and NAND growth profile? Thank you.
Bren Higgins -- Chief Financial Officer
Yes, I think I don't think it's going to, you know, it'll be a little bit stronger potentially in the second half than the first, but not much. Because, like I said earlier, the expected DRAM investments in China, I would expect in the second half to be lower than the first half.

[Operator instructions] I'll take our next question from Srini Pajjuri with Raymond James. Please go ahead. Your line is open.
Srini Pajjuri -- Raymond James -- Analyst
Sorry, I joined a little late, so if these questions have already been asked, I apologize. But I think last quarter, Bren, you had a customer push-out that kind of impacted your revenue for the year. I'm just wondering if there's any change or any update to that customer if you're including that in the current year's guidance.
Bren Higgins -- Chief Financial Officer
Yeah, it affected the March quarter as we had some shifting around, frankly, affected a little bit in the December quarter and the March quarter, but the shifting around to make the December quarter work, obviously, the shortfall was in March. So, I don't think anything has really changed. I don't expect to see much activity from that customer until we get into 2025. I mean, look, things could change.
We could see some surprises. But right now, at least from a planning point of view, we put it in 2025. And if it pulls in great, we can support it.
Srini Pajjuri -- Raymond James -- Analyst
Got it. Thank you. And then on the two-nanometer, I think your foundry customers are transitioning aggressively to get all around. Obviously, that helps you.
But at the same time, I think the EUV layer count is going to be somewhat flattish. So, I'm just wondering what sort of impact it will have on process control intensity if you go to GA and keep the, I guess, EUV kind of flattish in terms of layers. Should we expect any impact, or is it kind of a non-event for you?
Rick Wallace -- Chief Executive Officer
Oh, it's an event. I mean, our customers are definitely -- so you think about the dynamic. Our customers don't want to add process control intensity if they can avoid it. They also want to ramp and yield.
So, that's the trade-off. So, in the prototyping stage or the early pilot, they inspect more and they measure more in order to debug the process, if you will, and ramp it. And the question is, how much do they have to maintain when they ramp? And that's really what drives process control. They're definitely using more capability at the front end, and there's some areas where they're going to have to increase their sampling or measurement to keep up with the additional challenges of a smaller design role.
And there's also some new capability they have to bring because of FinFET. And so, we've talked in the past about modifications of a Gen 4 optical inspector to be able to support the FinFET. But it's not the only change in that process. So, the EUV layers matter, but the process integration challenges are still going to be there.
When we model it, though, we do see an increase. We have different scenarios for how much process control intensity will go up, but it's consistent with we think there will be a modest increase in the overall process control intensity for the leaders who have been successfully doing three nanometers. Anybody else that tries to jump to that node, though, will see a dramatic increase in their process control intensity because they don't benefit from the learning of having done three at volume. So, in aggregate, depending on how many people are supporting it over time, it will drive our intensity up for our customers.
We're also expecting a more robust design environment, certainly in the first few years, than what we saw with three-nanometer and likely a steeper ramp. So, in addition to the challenges of just the gate all around architecture, what it means from inspection, but also metrology, but also more volume earlier, steeper ramp, and a more robust design environment, which will challenge the customer's process integration more than you see when you just have a few designs. So, we're encouraged on a number of fronts.
Srini Pajjuri -- Raymond James -- Analyst
Got it. Thank you.

We'll take another question from Krish Sankar with TD Cohen. Please go ahead. Your line is open.
Krish Sankar -- TD Cowen -- Analyst
Hi. Thanks for doing my follow-up. Rick, I just had a follow-up on gate all around. Clearly, you have exposure to your Gen 4 optical inspection and the metrology for high-k metal gates.
Is there a way to quantify what you think your gate all-around revenues could be in calendar 2024?
Rick Wallace -- Chief Executive Officer
Yes. I'd be making it up, Krish. I mean, we don't really look at it that way. We do think about what is the node requirement.
So, from that standpoint, if you think N2, you'd attribute it all to gate all around. So, we think about node intensity for process control and blended. And as I said in the prior answer, that's slightly up, but we don't have a specific number specifically around gate all around. But obviously, that's the big driver for the change and why customers are pushing for N2.
And we don't know yet, but that's consistent with the 2026 model that we've had where we see rising process control intensity or corresponding increase per share for KLA.
Krish Sankar -- TD Cowen -- Analyst
Got it. That's helpful. And then just if I could squeeze one more in, I'm just kind of curious about your Gen 4 lead times. I think last time we said it was like seven to nine months.
As a change, if you assume that mature nodes are kind of slowing, China might moderate as the year progresses, is there a view that the lead times are coming in, or is it still like seven to nine months?
Rick Wallace -- Chief Executive Officer
Gen 4 is highly demanded across nodes. It's a very configurable system. And in fact, we recently introduced a non-upgradable version specifically for gate all around. So, it's a product that has a lot of extendability.
It's been challenged in terms of supply, the ability to get supply to meet demand. I would say, and we will see some increase this year in revenue from that system, which it hurt us last year just because we weren't able to get any incremental supply around key components. I'll see that increase this year, and so that will help. I still think lead times are probably in the 18-month to 24-month range for that product, although we do a lot of juggling to make sure that we're in position to support all of our customers.
But it has demand on multiple fronts, and I think it's a testament to its extendability and the favorability of a broadband system, which has the ability to scale the deployment lengths to meet very different inspection requirements across multiple nodes.
Bren Higgins -- Chief Financial Officer
Thank you, Krish. And I do think, Krish, you were referring to what we said about Gen 5, the seven to nine-month, a quarter-ago brand. So, I don't know on Gen 5 if there's any change there. No, Gen 5 is in the same ballpark.
Still the same ballpark. Perfect. All right. So, that brings us to the end of our call.
We want to thank everyone for your time and attention. We know it's a very busy day. With that, I will pass the call back over to our operator to conclude.
