Reuters reported on the 28th that two people familiar with the matter said ChangXin Technology plans to start small-batch production of HBM3E. HBM3E is an advanced high-bandwidth memory chip used with AI processors. According to the people familiar with the matter, ChangXin Technology has sent HBM3E samples to a number of domestic Chinese AI chip design companies. The people familiar with the matter said ChangXin Technology is expected to start small-batch production within the next two months. Because the relevant production plans have not yet been made public, the people familiar with the matter requested anonymity. High-bandwidth memory is manufactured by vertically stacking memory chips and can achieve high-speed data interaction with AI processors. It is a key component of dedicated chips used to train and run large language models.
