CXMT Surpasses 90% DDR5 Yield, Challenges Industry Giants

Chinese memory giant CXMT has reportedly achieved a significant milestone in DDR5 production, with manufacturing yields now comfortably above 90%. This is comparable to what major manufacturers like Samsung, SK hynix, and Micron are achieving. According to reports, CXMT uses a 17 nm node for DDR5 chip production and has reached a 90% yield for these chips. This is only 2-3% lower than Samsung's yield on its 10 nm class node for DDR5 production, indicating that CXMT's production quality is matching that of the world's largest memory maker. This is a remarkable achievement for a company that excels in cleanroom construction time, taking only 12 months to build its fab's cleanroom compared to the two years others require. As the company plans to end the year with 350,000 DRAM wafers per month, high yields mean there is little waste or leftover.

Chinese MyDrivers also notes that PC OEMs have mixed reactions to adopting CXMT DRAM in their products. For instance, Dell has completely banned the use of CXMT in its machines, while HP only allows CXMT DRAM in its Chinese PCs. Major Taiwanese brands such as ASUS and Acer have increased adoption in some models, as they have more flexibility in supply chain procurement. However, both companies use CXMT memory for PCs sold in mainland China and some emerging markets, meaning the West is still far from receiving PCs with CXMT memory modules. PC OEMs are also cautious about procuring CXMT memory due to concerns about disrupting their relationships with the big three memory makers.
