A significant new legal dispute has emerged that highlights the intensifying competition between Chinese and American tech firms. Yangtze Memory Technologies Co. (YMTC), China's leading memory chipmaker, has filed a patent lawsuit against US semiconductor company Micron Technology.
In the lawsuit filed in California, YMTC alleges that Micron infringed eight of its patents involving key technologies for manufacturing advanced 3D NAND flash memory chips.
The lawsuit centers on patents related to YMTC's pioneering multi-layer 3D NAND chip architectures, which enable greater data storage capacity on tiny memory chips. Specifically, the lawsuit centers on YMTC's 96-, 128-, 176- and 232-layer 3D NAND flash memory chip architectures. The more advanced 232-layer design was recently hailed as China's biggest chipmaking breakthrough to date.
YMTC asserts that threatened US firms like Micron have improperly utilized its patented 3D NAND innovations in an attempt to maintain competitiveness. However, Micron still holds a substantial lead with over 10% global market share in NAND flash memory compared to YMTC's 6% share.
YMTC's legal action signals its confidence in its own technological progress and desire to defend its patents against potential infringement. It also reflects China's ongoing efforts to foster domestic tech champions capable of competing with established US giants like Micron.
"This major patent dispute highlights how China's rapid rise as a semiconductor power is challenging US firms," said Chris Baxter. "It demonstrates how patents are becoming important strategic assets in the technology competition between the two nations."
