UFS 4.0 is backward compatible with UFS 3.1.

Kioxia Corporation, a world leader in memory solutions, today announced new consumer SSDs scheduled to be released in the third quarter of 2023. The EXCERIA PLUS G3 Series will leverage PCIe 4.0 technology and offer up to 2 terabytes (TB) of capacity. The new series is well-suited to mainstream users of high performance gaming PCs, desktops and notebooks, bringing the speed and affordability that they require. The EXCERIA PLUS G3 Series, which is a product under development, will be on reference exhibit at COMPUTEX TAIPEI from May 30 to June 2 at the Taipei Nangang Exhibition Center.

Featuring Kioxia's BiCS FLASH 3D flash memory TLC (Triple-Level-Cell), the EXCERIA PLUS G3 Series utilizes an M.2 2280 type single-sided form factor suitable for both desktops and mobile systems. The new drives will also support Kioxia's SSD Utility Management Software, which assists users with SSD monitoring and maintenance.

KIOXIA America, Inc. today announced the addition of the BG6 Series to its lineup of PCIe 4.0 solid state drives (SSDs) - the first product to feature the company's new, 6th generation BiCS FLASH 3D flash memory and almost 1.7 times the performance of its predecessor. Designed to unleash the increased speeds and affordability of PCIe 4.0 for PC users, the powerful and compact KIOXIA BG6 Series client SSDs offer a discrete M.2 2230 form factor with higher capacities and improved power efficiency. M.2 2280 single-sided form factor versions are also available.

The KIOXIA BG6 Series unlocks back-end flash performance while maintaining affordability and increasing capacity, making it an especially attractive option for commercial and consumer notebooks and desktops. KIOXIA BG6 drives support the fully matured Host Memory Buffer (HMB) technology, which utilizes part of the host memory (DRAM) as if it were its own, to realize a DRAM-less, high-performance SSD.

Due to the current lack of demand for NAND flash, the merger talks between Kioxia and Western Digital have picked up pace once again. The two companies have been at it since 2021 and it was reported back in January that the two companies once again wanted to try and combine their NAND production business. According to Reuters, the two have been pushed into the meeting room once again, largely due to the two NAND giants wanting to cut costs in a market where demand for their products isn't what it once was.

Kioxia and Western Digital are the second and fourth largest manufacturers of NAND flash, although all the memory is made in Kioxia's facilities. A merger of the two would create a company that is said to be owned at 43 percent by Kioxia and 37 percent by Western Digital, with current shareholders of the two companies getting the remaining 20 percent. However, a potential merger isn't without hurdles, as it's likely to be scrutinised by both the US and the PRC due to potential antitrust issues, with the combined company owning a third of the global NAND flash market. Kioxia has even shelved plans for a public offering, due to the sluggish demand for NAND flash. Time will tell if the two can come to an agreement, but it doesn't look like the best of times for a merger either.

The Chinese Government could retaliate to the U.S. ban on YMTC NAND flash memory products by banning American memory maker Micron Technology. This comes as the country initiated a "cybersecurity review" of Micron products to check if they conform to China's network security Laws. These are essentially the same grounds on which the US-FCC banned YMTC, forcing large customers like Apple to cancel orders of YMTC NAND flash products, derailing the company's growth. YMTC's 3D NAND flash products and their development roadmaps can be considered "contemporary," against those of Micron, Kioxia, SK hynix, and Samsung. If banned, China would force Chinese companies, such as Lenovo, HMD International, etc., to remove Micron from their qualified vendor lists.

Demonstrating continued innovation, Kioxia Corporation and Western Digital Corp. today announced details of their newest 3D flash memory technology. Applying advanced scaling and wafer bonding technologies, the 3D flash memory delivers exceptional capacity, performance and reliability at a compelling cost, which makes it ideal for meeting the needs of exponential data growth across a broad range of market segments.

"The new 3D flash memory demonstrates the benefits of our strong partnership with Kioxia and our combined innovation leadership," said Alper Ilkbahar, Senior Vice President of Technology & Strategy at Western Digital. "By working with one common R&D roadmap and continued investment in R&D, we have been able to productize this fundamental technology ahead of schedule and deliver high-performance, capital-efficient solutions."

Semiconductor manufacturers worldwide are forecast to increase 300 mm fab capacity to an all-time high of 9.6 million wafers per month (wpm) in 2026, SEMI announced today in its 300 mm Fab Outlook to 2026 report. After strong growth in 2021 and 2022, the 300 mm capacity expansion is expected to slow this year due to soft demand for memory and logic devices.

"While the pace of the global 300 mm fab capacity expansion is moderating, the industry remains squarely focused on growing capacity to meet robust secular demand for semiconductors," said Ajit Manocha, SEMI President and CEO. "The foundry, memory and power sectors will be major drivers of the new record capacity increase expected in 2026."

Kioxia, at the 2023 China Flash Market conference (CFM), unveiled its next-generation enterprise SSD powered by 2nd Gen XL-NAND flash memory that promises up to 13.5 GB/s of sequential reads on drives with PCIe Gen 5 x4 interfaces. This puts it higher than the 12-12.5 GB/s offered by the first crop of Gen 5 SSDs, and a 118% over its current crop of Gen 4 x4 SSDs. The drive also offers up to 9.7 GB/s of sequential writes.

4K random-access performance is of a lot more importance to enterprise customers, and here, the drive is said to offer up to 3 million IOPS random reads, with up to 1.06 million IOPS sequential writes. All this comes at a slightly reduced read-latency of 27 µs, compared to 29 µs for the previous generation. Kioxia also expects PCIe Gen 5 and CXL 1.0 to be the prominent I/O interfaces for enterprise SSDs from now until the end of 2025. It's only with 2026 that we could see the emergence of PCIe Gen 6 in the enterprise space, promising a doubling in interface bandwidth.

TrendForce's latest investigations reveal that the global NAND Flash market has been facing a demand headwind since 2H22. In response, the supply chain has been scrambling to clear out inventory, driving down NAND Flash contract prices by 20-25%. Enterprise SSD took the brunt of the fall with prices plummeting 23-28%. Despite manufacturers lowering prices in an attempt to drive up demand, clients are hesitant to purchase more components for fear of overstock. As a result, NAND Flash bit shipments rose by a mere 5.3% as ASP fell 22.8%. Global NAND Flash revenue was reported to be US$10.29 billion in 4Q22—down 25% QoQ.

TrendForce reports that Kioxia and Micron saw both a reduction in production and price in 4Q22. Kioxia's revenue plunged 30.5% due to weak demand from PC and smartphone clients and data centers readjusting their inventory. Micron generated a quarterly revenue of US$1.1 billion—a staggering 34.7% QoQ drop—that has led them to drastically decrease their capacity utilization rate for fabs. Luckily, Micron was able to ship their 232-layer client SSDs in 4Q22 as scheduled, and with the 176-layer QLC enterprise SSD hot on its heels, Micron's bit shipments are predicted to steadily improve in 2023 with their revenue climbing gradually quarter by quarter.

Looking back at 2H22, as server OEMs slowed down the momentum of their product shipments, Chinese server buyers also held a conservative outlook on future demand and focused on inventory reduction. Thus, the flow of orders for enterprise SSDs remained sluggish. However, NAND Flash suppliers had to step up shipments of enterprise SSDs during 2H22 because the demand for storage components equipped in notebook (laptop) computers and smartphones had undergone very large downward corrections. Compared with other categories of NAND Flash products, enterprise SSDs represented the only significant source of bit consumption. Ultimately, due to the imbalance between supply and demand, the QoQ decline in prices of enterprise SSDs widened to 25% for 4Q22. This price plunge, in turn, caused the quarterly total revenue from enterprise SSDs to drop by 27.4% QoQ to around US$3.79 billion. TrendForce projects that the NAND Flash industry will again post a QoQ decline in the revenue from this product category for 1Q23.

According to a report from Bloomberg, Western Digital and Kioxia are holding new talks about a potential merger of both companies' flash production businesses. The merger appears to be quite complex, as not only does it involve Western Digital spinning off its flash production business unit, which is then said to be merged with Kioxia, into what will be a publicly traded company in the US, but there will also be a second listing in Japan for the company.

Considering that Kioxia came out of Toshiba's DRAM and NAND flash manufacturing business, in which Western Digital was a partner until Toshiba divested its business into Kioxia. This caused quite some tension between the two companies, but Western Digital and Kioxia kept producing NAND flash in the shared facilities. The report by Bloomberg suggests that a management team from Western Digital will be running the combined company, which could potentially lead to future issues between the US and Japanese sides of the company. Time will tell if a merger will actually take place or not, as the two companies failed to come to an agreement in 2021, but it's possible that something has changed since then. Back in 2021, the merger was valued at US$20 billion plus.

KIOXIA is betting big on enterprise flash storage, and demoed several of its new and already-launched NVMe products based on the company's 162-layer 3D NAND flash memory, aka 6th Generation BiCS flash. Starting off, we see several single-chip solutions, namely the BiCS5 eTLC, the BiCS Industial TLC, and the BiCS5-QLC. These are complete NVMe SSDs on a single package, targeting embedded systems, industrial PCs, and the likes. They can even be directly embedded on server motherboards to serve as boot drives, freeing up precious chassis space for the main storage devices.

The EM6 is an enterprise network-attached SSD in a 2.5-inch form-factor. This is a NAS-on-a-stick that can be deployed at large scale, and accessible as a network resource, or as an NVMe-over-Fiber device. The CM7 is a high-capacity 2.5-inch (EDSFF E3.S) SSD that comes in sizes of up to 30 TB, and has PCI-Express 5.0 x4 interface with NVMe 2.0 protocol, with endurance of up to 3 DWPD and offering FIPS 140-33 security. We also see the XD6 line of EDSFF E1.S form-factor NVMe SSDs with PCIe 4.0 interfaces, up to 3.84 TB capacity, and 1 DWPD endurance.

This week at CES 2023, KIOXIA America, Inc., the inventors of NAND flash, will highlight new technologies, products, and form factors designed to meet upcoming IT requirements and standards - including PCIe 5.0 and UFS 4.0.

In an ever-changing technology landscape, where evolving standards push performance levels higher and higher, KIOXIA stands ready for what comes next - thanks to its broad, diverse lineup of flash storage solutions. "Whether it's the next connected vehicle, the next personal mobility device or the next smart city - we keep advancing flash memory to make the next thing possible," said Alex Mei, vice president of corporate marketing for KIOXIA America, Inc. "Countless consumer devices and applications require flash memory and SSDs, and we are committed to continued innovation."

It's not just TSMC and the other Taiwanese chip makers that are seeing a dip in demand, the Korean chip makers have seen a slump of 15 percent in the past four months, compared to 2021. This is said to be the biggest drop in chip demand since 2009 according to data from Statistics Korea. There's a combination of factors behind the slump in demand, especially when it comes to memory related products, where inventories already are high, combined with inflation and a low demand.

According to the Financial Times, an analyst at JPMorgan in Korea isn't expecting things to improve until 2024 at the earliest. Just like Micron and Kioxia, SK hynix is looking at cutting spending on new fabs and production lines, although as TPU reported earlier this week, Samsung is going its own way, by continuing to invest in new fabs and production lines. Samsung is expected to have a capex of US$37.5 billion this year back in October, although based on the increase in costs, the capex would have increased in the fourth quarter of the year. On the plus side, it seems like the shortage of semiconductors should ease in 2023 and hopefully return to more normal levels.

YMTC, the Chinese DRAM and NAND flash company that recently announced a 232-layer 3D NAND flash memory that threatened to disrupt entrenched players Samsung, Micron Technology, Kioxia, and SK Hynix, has been blacklisted by the U.S. Department of Commerce, forcing American consumer electronics and PC manufacturers to stop sourcing from the company. Capitalizing on just this, Samsung raised prices of its NAND flash memory chips by as much as 10%, according to a DigiTimes report.

YMTC peaked when Apple struck a NAND flash supply deal with the company in 2020, which would see its storage devices power pretty much every Apple product you can think of, however, under political pressure, Apple withdrew from this deal in 2022. The Department of Commerce contention has been to that YMTC has access to cutting-edge technology, and is backed by Chinese state-capacity, which can help it drive out competitors. All is not well between the U.S. and China geopolitically, either. Samsung's 10% increase in the first half of December 2022 concerns spot-pricing, which could mean its contract pricing (usually used by customers placing very large orders), could be different. It is conceivable that the exit of YMTC from the U.S. market could raise NAND flash product prices across the board.

TrendForce reports that the recent easing of tight supply for components has led to rising shipments for enterprise servers. Furthermore, ODMs for the most part have been able to sustain the momentum of data center build-out with the demand from ByteDance and the tenders issued by Chinese telecom companies. Nevertheless, the performance of the enterprise SSD market on the whole has been impacted by falling NAND Flash prices. For 3Q22, the NAND Flash industry's enterprise SSD revenue dropped by 28.7% QoQ to US$5.22 billion. Furthermore, all enterprise SSD suppliers recorded a negative performance for the period as well.

Regarding individual enterprise SSD suppliers' revenue figures for 3Q22, Samsung posted around US$2.12 billion. Its market share also shrank to 40.6% from 44.5% in 2Q22. Samsung's performance was mainly dragged down by the decline in its NAND Flash ASP. In the aspect of product development, SSDs featuring 128L NAND Flash and PCIe 4.0 will remain Samsung's main offerings for enterprise storage during 2023.

Market intelligence firm TrendForce reports that the whole NAND Flash market was severely weakened by plummeting demand in 3Q22. Because shipments of end products including consumer electronics and servers had been below expectations, the overall NAND ASP fell by 18.3% QoQ. Furthermore, the general economic outlook remained pessimistic, so enterprises across many sectors started to scale back their capital expenditure plans and halted the momentum of their procurement activities. Due to this development, the problem of excess inventory eventually spread to NAND Flash suppliers. The pressure on suppliers to make sales was ratcheted up dramatically. According to TrendForce's investigation, NAND Flash bit shipments fell by 6.7% QoQ for 3Q22, and the overall NAND Flash ASP also kept sliding. On account of the unfavorable market situation, the NAND Flash industry recorded a total revenue of around US$13.71 billion for 3Q22. The QoQ revenue decline reached as much as 24.3%.

The ranking of NAND Flash suppliers by revenue saw two notable changes for 3Q22. First, SK Group moved down to third place as it suffered the largest revenue drop among suppliers. Its revenue slipped by 29.8% QoQ to US$2.54 billion mainly due to the significant deterioration of the demand for PCs and smartphones. Its subsidiary Solidigm was also affected by the slowdown in server procurements. Previously, servers had a fairly stable demand situation compared with other kinds of end products. However, server demand eventually buckled in 3Q22 as result of enterprises cutting capital expenditure and undergoing a period of inventory correction. Compared with 2Q22, SK Group (that encompasses SK hynix and Solidigm) posted a drop of 11.1% in bit shipments and an even steeper decline of more than 20% in ASP.

Kioxia Corporation, the world leader in memory solutions, has developed an image classification system based on Memory-Centric AI, an AI technology that utilizes high-capacity storage. The system classifies images using a neural network that refers to knowledge stored in external high-capacity storage; this avoids "catastrophic forgetting," one of the major challenges of neural networks, and allows knowledge to be added or updated without the loss of current knowledge. This technology was presented on October 25 at the oral session of European Conference on Computer Vision 2022 (ECCV 2022) in Tel Aviv, one of the top conferences in the field of computer vision.

In conventional AI techniques, neural networks are trained to acquire knowledge by updating parameters called "weights." Once fully trained, in order to acquire new knowledge a neural network must be either re-trained from the beginning or fine-tuned with new data. The former requires huge amounts of time and consumes significant energy costs, while the latter requires parameters to be updated and faces the catastrophic forgetting problem of losing the knowledge acquired in the past which leads to deterioration of classification accuracy.

Kioxia Corporation and Western Digital Corporation today celebrated the opening of the state-of-the-art semiconductor fabrication facility, Fab7, at the Yokkaichi Plant in Mie Prefecture, Japan. Production capacity at Fab7 will ramp up in stages over time, in line with market trends. Total investment in phase one of Fab7 is expected to be approximately one trillion yen. Part of the capital investment in phase one of the Fab7 facility will be funded by a government subsidy that promotes cutting-edge semiconductor production facilities and ensures the stable production of semiconductors in Japan.

Fab7 has the capability to produce sixth-generation, 162-layer flash memory and future advanced 3D flash memory, is scheduled to start shipping 162-layer flash memory in early 2023. The facility uses artificial intelligence for enhanced production efficiencies and employs a space-efficient facility design that enlarges the space available for manufacturing equipment in its clean rooms. Fab7 is built for safety and sustainability, capable of absorbing earthquake shocks and implements the latest energy-saving manufacturing equipment.

Affected by tight wafer supply, lead time for SSD controller IC and PMIC components was prolonged to 32 weeks in 2021. All controller IC suppliers generally give priority to supplying NAND Flash manufacturers, so production at module factories could not meet SSD demand in the retail market during that time. In 2H21, the supply of SSD-related components improved quarter by quarter and various module manufacturers boosted their SSD shipments in order to upsurge their annual performance. According to TrendForce research, SSD shipments through global distribution channels reached 127 million units in 2021, with an annual growth rate of 11%.

This global SSD ranking is based on the shipment volume of module houses' own in-house brands in the distribution channel market as a standard for calculation and NAND Flash manufacturers are not included. NAND Flash manufacturer supply accounts for approximately 42% of the overall distribution channel market while module factory shipments account for approximately 58%. When SSD-related components were hard to come by, NAND manufacturers' supply chain management occupied a superior position compared to module houses, so NAND manufacturers' market share in the overall distribution channel market increased compared with 2020.

According to a TrendForce investigations, memory pricing began to decline from 4Q21 due to weakening demand for certain consumer electronics. Coupled with the impact of rising inflation, the Russian-Ukrainian war, and pandemic policies, demand in peak season was weak, resulting in inventory pressure that has extended from the buyer side to manufacturers. In response to the aforementioned situation, Micron announced last week that it would cut production of DRAM and NAND Flash, becoming the first major memory manufacturer to officially reduce its capacity utilization plan. In terms of NAND Flash, the market situation is more severe than that of DRAM. As the average contract price of mainstream capacity wafers has fallen to their cash cost and is approaching the periphery of selling at a loss for various manufacturers, Kioxia also announced that it will reduce NAND Flash capacity utilization by 30% from October on the heels of Micron's announcement.

In terms of DRAM, current contract pricing remains higher than the total production cost of various mainstream suppliers. Therefore, compared with NAND Flash, it remains to be seen whether there will be a significant reduction in production. In addition to mentioning the slight reduction in capacity utilization in this sector currently, Micron mainly emphasized its sharp downward revision of capital expenditures in 2023 and that the annual growth of DRAM production bits next year will only be around 5%. TrendForce believes, according to Micron, to actualize such conservative bit growth means that there is still room for a significant downward revision in capacity utilization and the extent to which Micron's subsequent production reductions are implemented remains to be seen.

The economic downturn keeps pushing the PC and related manufacturing markets down, following slumps in demand stemming from increased cost of living, the veritable arms race to technological products during COVID-19, and manufacturer's efforts to increase output to provide enough product to meet said demand. But all that goes up must eventually come down, and now South Korean manufacturers are facing the result of months of decreased consumption, with stock levels increasing ahead of actual product uptake (stocks have reached 67.3% of produced goods and factory shipments have declined 20.4%). This has now led to a 1.7% decline in August's output when compared to the same period last year - the first time the South Korean industry has seen negative growth since 2018.

Samsung and Kioxia both have announced a reduction in production output in the months to come, which should give distribution enough time to clear some of the accumulated inventory. The scales of production typically occur in cycles - ones with excess manufacturing against demand, and other times where the reverse happens. It seems we're now in the descending part of the spectrum, with prices - especially of NAND - being expected to drop in the coming months. It will take a while until the manufacturing reduction makes itself felt in the overall IC pricing landscape. Micron too has announced it's slowing down the production ramp-up of its 232-layer 3D NAND so as not to contribute in excess towards an already over-saturated market.

Kioxia Corporation, a world leader in memory solutions, today announced the industry's first 2 terabyte (TB) microSDXC memory card working prototypes. Using its innovative BiCS FLASH 3D flash memory and an in-house designed controller, basic functions of the KIOXIA 2 TB microSDXC UHS-I memory card working prototypes were confirmed in the microSDXC standard's maximum density.

As the data recording capacity of smartphones, action cameras, and portable game consoles continues to increase, the need for ultra-high capacity SD memory cards to store all of this data has never been higher. The SD Association's SDXC specification has supported memory cards up to 2 TB for more than a decade—but 2 TB cards have not been successfully manufactured until now.

KIOXIA America, Inc. is at Intel Innovation this week to demonstrate its CM7 Series NVMe SSDs that deliver next-generation levels of performance to enterprise and data center workloads.
