China’s CXMT Makes Breakthrough in Advanced Memory Chips

China’s leading memory-chip maker, ChangXin Memory Technologies, has begun producing advanced high-bandwidth memory in small quantities, a milestone that could ease a key constraint on the country’s development of homegrown AI processors.

CXMT is making HBM3E, an advanced type of high-bandwidth memory used in many of today’s leading AI processors, according to two people familiar with the matter.

That means its product is now only one generation behind the memory entering mass production at the world’s leading manufacturers, Samsung, SK Hynix and Micron Technologies.

CXMT plans to expand production in 2027, the two people added.
