Sanjay Mehrotra
President and Chief Executive Officer at Micron Technology
Thank you, Farhan. Good afternoon, everyone. Micron delivered an excellent performance in fiscal Q2, with results above the high end of our guidance.
We grew revenue and margins sequentially, while driving favorable mix and cost reductions amid ongoing global supply chain challenges. We saw broad-based demand for our products, with our SSD products achieving record revenue and our auto market revenue also reaching an all-time high. Execution was
Outstanding with our industry-leading 1-alpha DRAM and 176-layer NAND technology node ramps, delivering strong cost reductions. Our portfolio transformation continues to gain momentum, as we lead the industry on the DDR5 transition and grow our mix of NVMe data center SSDs.
Following a solid first half, we are on track to deliver record revenue and robust profitability in fiscal 2022 and remain well positioned to create significant shareholder value in fiscal '22 and beyond. In fiscal Q2, 1z and 1-alpha DRAM combined represented the majority of our DRAM bit shipments, while 176-layer NAND represented the majority of our NAND bit shipments. Our 1-alpha DRAM and 176-layer NAND products are achieving excellent yields, providing us with solid front-end cost reductions and contributing meaningful revenue. We qualified additional products on these advanced nodes with a broad set of customers, which sets us up for continued strong revenue ramp in the second half of the fiscal year.
We are tracking several quarters ahead of the industry in ramping products based on these leading-edge process technologies. We are also investing to maintain technology leadership for the next decade and making good progress in the development of future technology nodes. Micron is not only a technology leader, but also the industry leader in quality, with the majority of our customers ranking us No. 1. Our leadership in quality is an important differentiator for Micron, particularly in fast-growing data center and automotive markets, where our quality scores are excellent. We have also strengthened our position as a strategic supplier to our customers, as demonstrated by our commitment to supply continuity amid ongoing semiconductor supply chain challenges this past quarter.
In late December, a government mandated COVID-19 lockdown impacted production output at our backend facility in Xi'an, China. The Micron team executed with tenacity to return the Xi'an site back to normal output levels post lockdown. As a result of this outstanding effort, we mitigated the lost output from Xi'an
And delivered on our customer commitments for the quarter by leveraging our global manufacturing network. Additional COVID-19-related lockdowns in the region present a risk to the global electronics supply chain and we continue to monitor the situation closely.
The global semiconductor supply chain is experiencing pressure due to impact of Russia's invasion of Ukraine. The region is an important source for the global supply of noble gases and other critical minerals that are used in semiconductor manufacturing. We have strategically diversified our supply chain over the last several years and maintain appropriate inventories of materials and noble gases. We currently do not expect any negative impact to our near-term production volumes because of the Russia-Ukraine war, but we do expect an increase in our costs as we secure supply of certain raw materials that could be at risk. We also remain vigilant in this dynamic situation and are engaged with our key suppliers to ensure continuous availability of materials to support our operations.
Now let's review our end markets. Demand for memory and storage is broad, extending from the data center to the intelligent edge and to a growing diversity of user devices. Memory and storage revenue has outpaced the rest of the semiconductor industry over the last two decades and we expect this trend to
Continue over the next decade, thanks to ongoing advancement of AI, 5G and EV adoption. Our team's execution on strengthening our product portfolio has been outstanding, with several new product launches and customer qualifications in fiscal Q2, achievements that we are very proud of. Last year, data center became the largest market for memory and storage, eclipsing the mobile market.
Looking ahead, we expect data center demand growth to outpace the broader memory and storage market over the next decade, fueled by secular drivers in cloud and healthy enterprise IT investment. Memory and storage share of server BOM costs already exceeds 40% and this number is even higher for servers optimized for AI/ML workloads. This growth is supported by new heterogenous computing architectures, the increase in data-intensive workloads and the ongoing displacement of HDDs by SSDs.
In the fiscal second quarter, data center revenue grew more than 60% year-over-year, supported by robust demand across our DRAM and SSD portfolio. We have broadened the qualifications for our 1-alpha DRAM products and are well positioned to support the data center DDR5 transition driven by new CPU
Platforms, which are targeted to begin ramping later this calendar year and gain momentum in 2023. Following the introduction of our 7400 SSD, in fiscal Q2 we introduced the 7450, which is the industry's first 176-layer vertically integrated data center NVMe SSD. These Gen4 NVMe data center drives are generating an enthusiastic response from our customers.
We are making robust progress in our qualifications of these drives with data center customers, which has contributed to a doubling of our fiscal Q2 data center SSD revenues year-over-year. We expect strong growth of data center SSD revenues to continue for the remainder of this fiscal year. In fiscal Q2, we saw recovery in our client revenue, driven by strength in enterprise PCs, which more than offset softer consumer and Chromebook demand. We expect that calendar 2022 PC unit sales will be flattish versus last year's sales, but we expect solid growth in DRAM and NAND content, driven in part by increasing mix of content-rich enterprise desktops and laptops. We are leading the industry's client DDR5 transition and our DDR5 revenue continues to increase as multiple PC customers launch next generation notebooks.
Client DDR5 demand continues to outstrip supply and we are seeing meaningful price premiums over DDR4 alternatives. Building on our QLC leadership, in fiscal Q2 we also launched our 2400 NVMe SSD, the world's first client SSD built on 176-layer QLC NAND. Micron maintains a leading position in the fast-growing graphics market. We have a broad product portfolio featuring industry-leading product performance and deep partnerships with leading GPU
Suppliers. In fiscal Q2, revenues grew year-over-year, driven by strong demand for the latest generation of gaming consoles and graphics cards.
Our advanced GDDR6X continues to lead the industry in performance and in fiscal Q2, we began revenue shipments of our next-generation GDDR6X solutions. Fiscal Q2 mobile revenue grew slightly year-over-year as the 5G transition continues in smartphones. We see some weakness in the China market as the local economy slows, smartphone market share shifts and some customers take a more prudent approach to inventory management.
Mobile memory and storage demand continues to be supported by content-hungry applications and the ongoing transition from 4G to 5G, which is driving 50% higher DRAM content and a doubling of NAND content. 5G smartphone sales are expected to grow to 700 million units in calendar year 2022. In fiscal Q2, we achieved the first qualification of our 1-alpha LP5 DRAM, which delivers more than a 15% power improvement over the previous generation, enabling our customers to offer an improved 5G experience with better battery life.
We are also seeing a very strong revenue ramp for our 176-layer NAND UFS products, which are now qualified in nearly 50 different OEM platforms. The automotive and industrial segments are expected to be the fastest-growing memory and storage markets over the next decade. Today, more than 10% of our revenue comes from these end markets and we are exceptionally well positioned as the market share leader.
In fiscal Q2, our auto revenues set a new record, driven by robust demand for memory and storage. Auto unit production remains below demand, constrained by numerous supply chain challenges, including logic and analog semiconductor component shortages. The Russian invasion of Ukraine has also impacted
Auto builds. Nevertheless, the demand for memory and storage remains strong, driven by auto content growth.
New EVs are becoming like data centers on wheels and we expect over 100 new EV models to launch worldwide in this calendar year alone. These new EVs include advanced ADAS and in-vehicle infotainment features that have significantly higher memory and storage requirements. In fact, some of these level-3 autonomous EVs have about $750 in memory and storage content, which is 15 times higher than the average car. In industrial IoT, we saw approximately 60% year-over-year revenue growth, fueled by the continued ramp in applications such as factory automation and security systems.
Turning to the market outlook. Our expectation for calendar 2022 industry demand is largely unchanged from our last earnings call. We expect calendar 2022 industry bit demand growth to be in the mid to high teens for DRAM and at approximately 30% for NAND. We anticipate underlying demand in calendar 2022 to be led by data center, ongoing adoption of 5G smartphones and continued strength in automotive and industrial markets. Currently, we see a healthy supply-demand balance across both DRAM and NAND, given these demand trends, supply discipline across the memory industry, long semiconductor manufacturing equipment lead times and reduced NAND supply from some of our competitors that experienced a contamination issue in their fab.
Non-memory component shortages are improving and we expect that further improvements should support memory and storage demand growth for rest of this year. However, there are some pockets where semiconductor shortages have not improved as fast as we had expected and these shortages are likely to continue into calendar year 2023. We are mindful of increased macroeconomic uncertainty and remain vigilant of any changes in market conditions.
Turning now to Micron's bit supply growth expectations for the year. Consistent with the rest of the industry, we are experiencing a challenging environment for equipment and material supplies. However, due to strong execution by Micron's operations team, our calendar year 2022 bit supply growth for DRAM
And NAND remains unchanged from prior expectations and will be in line with industry demand. We are on track to deliver record revenue with solid profitability in fiscal year 2022 and we continue to expect strong bit shipment growth in the second half of the fiscal year.
We expect our cost reductions to outpace that of the industry this year driven by the exceptionally well executed ramp of our world class 1-alpha DRAM and 176-layer NAND nodes. However, across the industry there are cost challenges stemming from supply chain and inflationary pressures which will limit cost
Reductions this year for the industry. We remain confident in our long-term technology roadmap and our ability to drive competitive cost reductions for years to come.
I will now turn it over to Sumit.
