Yangtze Memory Technologies Corp (YMTC) is a Chinese semiconductor integrated device manufacturer specializing in flash memory (NAND) chips. Founded in Wuhan, China in 2016 with government investment and a goal of reducing the country's dependence on foreign chip manufacturers, the company was formerly a subsidiary of partially state-owned enterprise Tsinghua Unigroup. Its consumer products are marketed under the brand Zhitai. As of 2020, YMTC is using a 20 nm process to make 64-layer 3D NAND flash. In April 2020, the company unveiled its first 128 layers vertical NAND chip based on Xtacking architecture, which has since entered production. From Wikipedia
