U.S. Entity List: YMTC (Dec 2022)

The U.S. Department of Commerce added YMTC — China's largest 3D NAND flash maker — to the Entity List on December 15, 2022. The action was motivated by concerns that YMTC had supplied NAND chips to Huawei in violation of U.S. restrictions, and by the broader goal of preventing YMTC from acquiring U.S.-origin equipment and technology needed to scale its 232-layer Xtacking NAND to volume production. Apple's plan to qualify YMTC chips as an iPhone supplier was halted following the listing.
