Yangtze Memory Technologies Co., Ltd. (YMTC), a benchmark in China's memory chip industry, was established on July 26, 2016, in Wuhan, Hubei Province. It is a state-owned enterprise and the only company in mainland China with complete IDM (Integrated Device Manufacturer) capabilities for 3D NAND flash memory. Its headquarters are located in the Wuhan National Memory Base. It has R&D centers in Beijing and Shanghai, and a global marketing network; its retail brand is ZhiTai.

1. Xtacking® architecture is the core technology, which involves manufacturing memory cells and peripheral circuits in separate slabs and then hybrid bonding them, significantly improving performance, density, and mass production efficiency. It has been iterated to version 4.0; 64-layer mass production began in 2019, with 128/232/294-layer 3D NAND subsequently launched.

2. Product lines cover 3D NAND wafers/chips, eMMC/UFS embedded storage, consumer-grade (PCIe 4.0/5.0 SSDs), and enterprise-grade data center storage solutions.

3. A rich patent portfolio, including numerous international invention patents, and a 3D NAND hybrid bonding patent licensing agreement with Samsung is expected in 2025.

4. Industry position: The rise of Yangtze Memory Technologies Co., Ltd. (YMTC) has broken the long-standing monopoly of the global flash memory market held by American, Japanese, and Korean companies such as Samsung, SK Hynix, Micron, and Kioxia. With its self-sufficiency in data center memory chips, YMTC is a core pillar enterprise of China's semiconductor memory industry.
