China’s cybersecurity regulator has banned Chinese companies from buying chips from US memory maker Micron Technology. , the Cyberspace Administration of China (CAC) said Sunday that it found that the company’s products pose a “significant security risk” to China’s critical information infrastructure, including banks owned by state and telecom operators. The ban comes after China announced a review of Micron imports in late March in a move seen at the time as retaliation for sanctions imposed by Washington on Chinese chipmakers in recent years. .
Idaho-based Micron is the largest memory manufacturer in the US. The Chinese market accounts for about 10 percent of the company’s annual revenue, although most of the companies that import Micron’s products to China are manufacturers that make devices for sale in other parts of the world. . According to The Wall Street Journal, the CAC ban does not apply to non-Chinese companies in China. “We are reviewing the conclusion and evaluating our next steps,” Micron. “We look forward to continuing to engage in discussions with the Chinese authorities.” The CAC did not say which Micron products would be affected by the ban, nor did it share details about what security concerns the company’s chips have.
The ban is the latest development in a growing semiconductor technology dispute between the US and China. In recent months, the Biden administration has moved to restrict its opponent’s access to advanced chip-making equipment. In January, US, Dutch and Japanese officials of lithography machines from ASL, Nikon and Tokyo Electron. as The Journal note, China is trying to find ways to get back at the US. Micron is an easy target given that most Chinese companies can turn to suppliers like South Korea’s SK Hynix to make up for any shortfall left by a ban.
