Micron Chip Sales Banned in China, UMC Says
A Chinese court temporarily banned Micron Technology Inc. chip sales in the world's largest semiconductor market, Taiwanese rival United Microelectronics said.
In a patent ruling in favor of UMC, the Fuzhou Intermediate People's Court of the People's Republic of China issued a preliminary injunction stopping Micron from selling 26 products, including dynamic random access memory and Nand flash memory-related products, UMC said in a statement Tuesday. Micron said it hasn't been served with the injunction.
Last December, Micron filed a civil lawsuit in the state of California, accusing UMC of secret infringement of intellectual property related to its DRAM chips. In January, UMC filed a patent infringement lawsuits against Micron.
Earlier in the day, UMC said the injunction stops Micron from selling certain DRAM and NAND-related items, including solid-state hard drives and memory sticks in China.
