SK Hynix, a semiconductor leader, announced a significant breakthrough in NAND flash technology on August 9 at the Flash Memory Summit in California. They introduced a pioneering 321-layer 1Tb TLC 4D NAND flash memory, marking a notable advancement in NAND capabilities.

As the first company in the industry to surpass 300 layers in NAND development, SK Hynix plans to refine the 321-layer NAND for mass production by mid-2025. This leap builds upon their expertise gained from 238-layer NAND production, showcasing their commitment to pushing technological boundaries.

The efficiency of the 321-layer NAND is 59% higher than its 238-layer predecessor, attributed to enhanced data storage unit stacking. This translates to increased storage capacity and improved chip output per wafer.

In response to the growing demand for high-performance memory solutions in the AI market, SK Hynix unveiled next-gen NAND products, including PCIe 5-equipped enterprise SSDs and UFS 4.0 solutions, catering to the increasing need for advanced storage.

SK Hynix’s dedication to innovation is further emphasized by its ongoing development of PCI 6.0 and UFS 5.0 products, solidifying its market leadership position. Meanwhile, VP of SK Hynix NAND Flash Development, affirmed their commitment to leading the NAND technology domain with the development of fifth-gen 321-layer 4D NAND, tailored to the AI era.

DRAM Spot Market
Regarding recent developments in the spot market, there have been sporadic price upticks for low-priced DDR4 products. Meanwhile, prices of DDR5 products have kept falling due to the plentiful chip supply. Unlike the contract market, the spot market has been relatively unaffected by discussions about the possibility of price hikes, and spot trading as a whole is rather tepid. Furthermore, module houses were previously quite aggressive in stocking up, so they are now eager to sell as their inventories remain at a fairly high level. The average spot price of the mainstream chips (i.e., DDR4 1Gx8 2666MT/s) dropped by 0.13% from US$1.517 last week to US$1.515 this week.

NAND Flash Spot Market
Spot market demand, different from that of the contract market, remains relatively sluggish recently, where concluded prices are still dropping due to sufficient stocks, despite a slight increment in price inquiries. 512Gb TLC wafer spots have dropped by 0.28% this week, arriving at US$1.413.

YMTC has officially notified a 3~5% price increase for NAND Flash in mid-May. However, the initial impact of the price hike is expected to be felt in the enterprise market, and it may take some time to reflect in the consumer spot market.

The semiconductor industry is in the midst of a correction period aimed at tackling inventory challenges, and the memory sector is feeling the impact. Major players in global memory manufacturing, including Samsung, SK Hynix, Micron, and YMTC, have recently disclosed substantial cuts in CAPEX, ranging from 45~50% starting from 4Q22. The most recent financial reports from Micron and Samsung further underscore the industry’s downward trend.

TrendForce highlights that YMTC’s decision to raise prices comes amidst market conditions marked by substantial oversupply in the second quarter. Despite Samsung’s efforts to curtail production, the positive effects of this reduction are not anticipated to materialize until the latter part of the year. Consequently, experts predict a more substantial decline in contract prices for the second quarter of 2023 than initially expected.

The market situation in 2Q23 is still oversupplied, leading to further price declines. Since October of last year, the market transaction price for wafers has been lower than the supplier’s cash cost due to selling pressure. Some suppliers used the opportunity when Samsung announced production cuts to raise the wafer price, which is likely why YMTC made this announcement.

TrendForce’s latest research indicates that, as production cuts to DRAM and NAND Flash have not kept pace with weakening demand, the ASP of some products is expected to decline further in 2Q23. DRAM prices are projected to fall 13~18%; NAND Flash is expected to fall between 8~13%.

On the other hand, based on the weekly updates on the DRAM and NAND flash spot markets by TrendForce, the spot markets for DRAM and NAND flash continued to decline this week. Details are as follows.

DRAM Spot Market

Spot prices of DDR4 products have been dropping incrementally for several consecutive days, and buyers in the spot market are mostly waiting for further developments. However, there are more quote inquiries for DDR5 products because the supply gap hasn’t been bridged. As a result, there is now an uptick in spot prices of DDR5 products, and the divergence between DDR4 and DDR5 products in terms of price trajectory is expected to continue for several weeks. Nevertheless, spot prices of DDR4 products are showing no sign of rebounding in the near future. The average spot price of mainstream chips (i.e., DDR4 1Gx8 2666MT/s) fell by 0.74% from US$ 1.618 last week to US$ 1.606 this week.

NAND Flash Spot Market

European and American spot markets have yet to recover in purchase sentiment, while some Asian markets, due to the recuperation of the Chinese market, have slightly risen in purchase willingness. Overall spots have not experienced any apparent fluctuations from South Korean suppliers’ announcement of production cuts, despite sellers aggressively adjusting their prices and pursuing orders, which led to a restricted level of overall transactions and a small drop in prices. 512Gb TLC wafer has dropped by 0.35% in spot prices this week, arriving at US$1.431.

According to TrendForce research, looking at NAND Flash wafers, the pricing of which more sensitively reflects the market, suppliers are increasingly motivated to cut prices in exchange for sales due to weak retail demand since March and a more conservative outlook for shipments of other end products. The price of NAND Flash wafers is expected to begin falling in May and the supply of NAND Flash will gradually overtake demand in 2H22. The price decline of NAND Flash wafers in 3Q22 may reach 5~10%.

At the same time, TrendForce indicates that February’s contamination incident at Kioxia was expected to tighten the market in 2Q22 and 3Q22. However, as a consequence of rising inflation and the war between Russia and Ukraine, market demand for consumer products in the traditional peak season of the second half of the year is trending conservative and the prices of client SSD, eMMC, and UFS in 3Q22 will be flat compared to 2Q22, breaking from the original expectation that prices may rise. In terms of enterprise SSDs, as demand for data centers remains strong, no significant correction in demand has yet been observed. However, as the overall NAND Flash market gradually moves into oversupply, prices will only grow slightly by approximately 0~5% in 3Q22.

Weakening demand in a period of unabated production expansion, NAND Flash may face oversupply in 2H22

From the perspective of demand, due to the war between Russia and Ukraine, rising inflation, and the pandemic in China, overall demand for consumer electronics is weak. Demand for Chromebooks dwindled rapidly at the beginning of 2022 as exogenous demand from the pandemic disappeared. In terms of conventional notebooks, the situation with commercial models and consumer models present a divergence. Demand for commercial notebooks is benefiting from a return to the office occurring in many countries, while the opposite is true for consumer notebooks. Therefore, overall demand for notebooks in 2022 will be lower compared to demand in 2021. In terms of smart phones, the production volume of Chinese brands has been suppressed due to China’s flailing against the pandemic and government lockdowns stemming from a continued insistence on a dynamic zero-COVID policy, resulting in continuous downward revisions of global smart phone production for 2022.

In terms of supply, Samsung is focusing on substantial future growth in the enterprise SSD sector and continues to maintain its original capacity expansion plan, especially after its NAND production line was derailed due to the Xi’an lockdown at the end of last year. In order to stabilize future plant operations, the capacity of its P2L fab in South Korea continues to increase. Yangtze Memory Technologies (YMTC) will also expand its wafer input plan in 2H22. Since the 128L yield rate has reached the company’s goal and it had successfully broken into the tier 1 smartphone supply chain in 1H22, YMTC will also accelerate production at its second factory in Wuhan. Therefore, TrendForce indicates, since an overall weakness in demand will linger in 2022 yet certain manufacturers will maintain a pattern of expanding production, the NAND Flash market will face oversupply in 2H22. As mentioned above, the prices of various products will be flat or experience reduced growth in 3Q22.
