ChangXin Memory Technologies will start limited production of HBM3E chips over the next two months despite yields of just 20%, two people familiar with the matter said. The move highlights China's drive to match NVIDIA CORP's processors amid United States export curbs. Low yields threaten to make domestic hardware substantially more expensive than foreign alternatives.
