Jiangsu Advanced Memory Semiconductor Fabs

Jiangsu Advanced Memory Semiconductor Co., Ltd. (JSAMSC) was a Chinese phase-change memory (PCM) manufacturer established in October 2016 in Huaian, Jiangsu Province. It aimed to develop 3D XPoint-class PCM technology on a 12-inch (300mm) fab with planned capacity of 100,000 wafers/year (investment: RMB 13 billion / ~$1.78B). First-generation PCM chips were developed by 2019, but funding collapsed by 2020. Formal bankruptcy and liquidation was accepted by Huaian court in July 2023; a final rescue attempt by Huaxin Jiechuang collapsed in 2025.
