U.S. Considers Restricting China's Access to AI Memory Chips

The U.S. is considering unilateral restrictions on China’s access to AI memory chips and equipment capable of making those semiconductors as soon as next month, a move that would further escalate the tech rivalry between the world’s biggest economies. The measure is designed to keep Micron Technology Inc. and South Korea’s leading memory chipmakers SK Hynix Inc. and Samsung Electronics Co. from supplying Chinese firms with so-called high-bandwidth memory, or HBM, chips, according to people familiar with the matter, who emphasized that no final decision has been made.
