CXMT Surpasses 90% DDR5 Yield, Approaches Industry Standard Quality

Posted on
Chinese DRAM manufacturer CXMT achieves 90%+ DDR5 yield on 17nm node, narrowing gap with Samsung and challenging memory giants worldwide.

Quick Report

Chinese memory giant CXMT reached a significant manufacturing milestone, achieving DDR5 yields above 90% using a 17nm node—comparable to Samsung's yields on its 10nm class node, with only a 2–3% difference. This demonstrates CXMT's production quality has caught up to the world's largest memory makers, bolstering the company's position as a viable global DRAM supplier.

CXMT plans to end the year with 350,000 DRAM wafers per month production capacity, with high yields meaning minimal waste. PC OEM adoption remains cautious, however: Dell has completely banned CXMT DRAM, HP allows it only in Chinese PCs, and major Taiwanese brands like ASUS and Acer show limited Western adoption while using CXMT more liberally in China and emerging markets. The mixed response reflects concerns about disrupting relationships with Samsung, SK hynix, and Micron, though all 2027 capacity from the big three is reportedly sold out, forcing OEMs to consider CXMT for additional supply.
