CXMT reportedly plans limited HBM3E production despite 20% to 30% yields

September reports from The Korea JoongAng Daily, Tom's Hardware, and The Information said ChangXin Memory Technologies had begun small-scale or risk production of HBM3E. Reuters reported on October 28 that CXMT had sent samples to domestic AI chip designers and expects to begin limited production within two months. Its sources say only 20% to 30% of chips meet specifications, amid U.S. restrictions on advanced chipmaking equipment.
