Micron Technology has petitioned the U.S. Supreme Court to reverse previous rulings that allowed Chinese memory chipmaker Yangtze Memory Technologies Co. (YMTC) access to 73 pages of Micron's confidential 3D NAND technology documents, citing national security concerns. This legal dispute follows YMTC's lawsuit filed in federal court in Washington on June 6, accusing Micron and the public affairs firm DCI Group of spreading false claims that YMTC's chips pose a threat to U.S. national security. YMTC alleges that Micron and DCI disseminated falsehoods suggesting the Chinese company installed spyware on its chips at the behest of the Chinese government, describing these claims as "xenophobic lies." The case highlights escalating tensions between the two semiconductor companies amid broader geopolitical and trade concerns.
