- 1China's CXMT to begin producing advanced HBM3E AI memory chips●China's CXMT plans to start production of HBM3E, an advanced type of high-bandwidth memory chip used with AI processors,
Chinese memory chipmaker CXMT plans to start production of HBM3E, an advanced high-bandwidth memory used alongside AI processors. Sources say the move is proceeding despite significant quality problems, with as little as 20% of the chips the company makes currently usable. The plan signals China's push to build domestic AI semiconductor capability despite yield challenges and foreign export controls.

Chinese memory maker CXMT plans to begin mass production of HBM3E high-bandwidth memory chips in the fourth quarter of 2026, despite reportedly poor production yields. The move would push China further into the advanced memory segment dominated by SK Hynix, Samsung and Micron, and is drawing attention given US export controls restricting China's access to cutting-edge chip technology.
