[Sources: Changxin Memory Plans Mass Production of HBM3E, Yield Rate Only 20% to 30%] According to Reuters, two sources familiar with the matter revealed that Changxin Memory plans to begin small-scale mass production of its HBM3E high-bandwidth memory within the next two months. Currently, its yield rate is only about 20% to 30%, compared to SK Hynix's approximately 70%. Changxin has already sent samples to several domestic AI chip design companies. In testing, its performance is closer to SK Hynix's previous generation product, the HBM3. US export controls have led to a shortage of high-end memory for Chinese AI chip companies, with Huawei, Cambricon, and others raising AI chip prices by 20% to 50% last month. Changxin's HBM3E is expected to cost more than similar overseas products.
