Mitsubishi reaches an agreement with Rambus
An agreement has now been reached between Mitsubishi Electric and Rambus Inc. on patent licenses for SDRAM, DDR SDRAM and the associated memory controllers. Mitsubishi now has to pay license fees to Rambus Inc. retrospectively from July 1st, 2000 for the memory technologies and the agreement reached.
The fees for DDR SDRAM are higher than those for Direct Rambus memory. Mitsubishi, like Samsung, NEC, Hitachi, Toshiba and Oki, has thus reached an agreement with Rambus Inc.; Together these companies had a 40 percent share in the production of DRAM in 1999. So far, Infineon, Hyundai and Micron have refused to enter into such an agreement with Rambus because they are of the opinion that Rambus' patents are ineffective because they are based on technologies that the storage companies discussed in joint discussions between 1993 and 1995. They are likely to be sued by Rambus or they are suing Rambus themselves.
