Yangtze Memory Technology Corp

Yangtze Memory Technologies Corp., or YMTC, was founded on July 26, 2016, in Wuhan, Hubei Province, with a total investment of US$24 billion from Tsinghua Unigroup, the Hubei provincial government, and the state-owned China Integrated Circuit Industry Investment Fund. The company was created to break China's dependence on foreign memory chip suppliers like Samsung, SK Hynix, and Micron. Its R&D actually began two years earlier, in 2014, with the first test chip design completed in 2015.

YMTC is an integrated device manufacturer specializing in 3D NAND flash memory. Its proprietary Xtacking architecture, which won Best of Show at FMS 2018, manufactures memory and logic circuits on separate wafers and bonds them together. The company has shipped five generations of NAND, from Gen 1 in 2018 to Gen 5 (X4-9060 TLC and X4-6080 QLC) entering mass production in 2024-2025. Xtacking 4.0 won Most Innovative Technology Award at FMS 2025.

By Q3 2025, YMTC captured 13% of global NAND shipments, closely trailing Micron for fourth place. The company sells enterprise SSDs under its own brand and consumer SSDs under the ZhiTai label in China. It supplies chips to Lexar, HP, Acer, Kingston, and Teamgroup. YMTC's valuation reached roughly US$22-23 billion after a 2025 capital injection, and it ranked 32nd on the 2026 Global Unicorn List.

Geopolitical friction has marked YMTC's recent history. In 2022, the U.S. designated YMTC as a restricted entity, limiting access to American technology. Apple paused procurement plans for YMTC memory. In December 2025, YMTC sued the U.S. Defense Department over its inclusion on a military-linked entity list. The company also filed a patent infringement lawsuit against Micron. Despite these challenges, YMTC continues expanding, opening new offices in Singapore in 2026 and investing in fabrication facilities to boost wafer output. [edit]
