China's CXMT to begin producing advanced HBM3E AI memory chips

Original: 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.

Why now: It highlights China's accelerating efforts to achieve self-sufficiency in advanced AI chips despite technical setbacks.
