China's CXMT debuts HBM3E chips, narrowing AI memory gap

china's changxin memory technologies (cxmt) has begun producing its first hbm3e chips in small quantities, according to a report from the information. hbm3e is a type of high bandwidth memory used in many current ai processors to train and run large ai models. cxmt is currently a generation behind samsung, sk hynix, and micron, which are mass-producing hbm4. alibaba's t-head and cambricon are testing cxmt's hbm3e and plan to use it in products starting 2027, which could help chinese ai chips overcome limitations imposed by us export rules. cxmt faces technical challenges, with low yields estimated at around 25 percent in june and is considered three to five years behind its competitors.
