Rambus Sues Two Companies for Violating Chip Patents

Rambus announced that it had filed suit against Hynix Semiconductor, Taiwan's Nanya Technology and Infineon Technologies, as well as the latter two companies' joint venture, Inotera Memories, for allegedly violating its intellectual property in producing DDR2 DRAM, which started to get incorporated into PCs last year. The suit, filed in the U.S. District Court for the Northern District of California, alleges that the GDDR2 and GDDR3 memory found on graphics cards violates its patents.
