According to people familiar with the matter, the Biden administration is aiming to restrict China’s access to chip hardware that is just beginning to enter the market. The sources reported that among the measures being discussed is limiting China’s ability to use a cutting-edge chip architecture known as gate all-around (GAA). GAA technology enables more powerful chip production, and chip makers including Nvidia, Intel, AMD and TSMC aim to begin mass-producing GAA-architecture chips next year. The sources said the U.S. aim is to control China’s access to the nascent technology before it is commercialized. Following the news, Nvidia shares fell as much as 2.5 percent on Tuesday, while AMD lost 1.9 percent and Intel lost 1 percent.
