➀ Micron challenges court rulings that allowed YMTC access to 73 pages of confidential 3D NAND documentation, citing national security risks;

➁ The dispute stems from a 2023 patent infringement case where YMTC accused Micron, with Micron arguing YMTC's request for printed source code pages exceeds agreed limits;

➂ Under the protective order, YMTC's access is restricted to physical copies with strict anti-duplication rules, though Micron seeks Supreme Court intervention to revoke access entirely.

➀ Yangtze Memory Technologies (YMTC) is shipping a TLC NAND with 294 layers, 232 of which are active;

➁ The new device has the same number of active layers as the company's previous generation NAND;

➂ The reason for the increase in dummy layers is unclear.
