[News] SK hynix and Samsung Reportedly to Reduce Legacy DRAM Production like DDR4


2024-11-05 Semiconductors editor

As South Korean memory giants Samsung and SK hynix announced their third quarter financial reports, posting a 112% and 94% year-over-year revenue growth, respectively, the threat from increasing output of Chinese rivals such as CXMT, which drives prices down, has reportedly prompted them to significantly cut back on legacy memory chip production, according to the report by the Korea Economic Daily.

According to the report, China’s ChangXin Memory Technologies (CXMT) has been ramping up the production of older chips like DDR4 and LPDDR4X, resulting in severe price pressure in legacy products.

CXMT has expanded its monthly DRAM production capacity from 40,000 wafer sheets in 2020 to 160,000 sheets. This capacity is expected to reach 200,000 sheets by year-end and 300,000 by the close of 2025, the report said.

SK hynix to Reduce DDR4 Production to 20% of Total DRAM Output

Industry sources cited by the report noted that in a recent investor relations session with Goldman Sachs, SK hynix suggested that it plans to reduce DDR4 DRAM production to 20% of its total DRAM output by the end of the year, down from 30% in September and 40% in June.

On the other hand, according to the report, in an earnings call with analysts on last week, Kim Jae-joon, executive vice president of Samsung’s device solutions (DS) division, confirmed plans to reduce production of legacy DRAM and NAND flash chips, aligning with industry expectations that chipmakers are scaling back on conventional memory output.

HBM and eSSD Emerge as the New Focus

Instead, both memory giants highlighted in their earnings call that they would shift their focus to highly profitable premium products like HBM and enterprise solid-drivers (eSSDs).

These adjustments by Samsung and SK hynix align with strong server DRAM demand driven by major tech firms like Google and China’s Baidu investing in server infrastructure, while PC DRAM sales have remained stagnant, according to the Korea Economic Daily.

According to SK hynix, as generative AI is developing into a multi-modal1 form and global big tech companies continue to invest to develop artificial general intelligence (AGI), the demand of memory for AI servers such as HBM and eSSD has grown noticeably this year. SK hynix predicts that this trend will continue next year.

According to the Korea Economic Daily, anticipating a prolonged global over supply, SK is accelerating the upgrade of its older DRAM lines in Wuxi, China, to advanced lines for producing fourth-generation 10-nanometer 1a DRAM.

While maintaining steady NAND flash production, in the meantime, SK is increasing the operation rate at its eSSD facility in Dalian, China, to nearly full capacity, according to sources cited by the report.

On the other hand, Samsung noted that in 2025, the company plans to expand the sales of HBM3E and the portion of high-end products such as DDR5 modules with 128GB density or higher for servers and LPDDR5X for mobile, PC, servers, and so on.
