Sega Enterprises and Sega of America have been named in a suit brought against Hitatchi by Rambus. Rambus has requested that the United States International Trade Commission investigate the importation of Hitatchi SDRAM and DDR SDRAM that Rambus says infringes on its patents. Rambus further hopes to stop the importation and sale of the offending memory, including microprocessor and memory products used in Sega's Dreamcast console. Rambus has a total of eight patents involved in two separate suits originally filed in January and February.
