Rambus patent-infringement trials put on hold
A U.S. federal judge on Tuesday postponed indefinitely the coordinated patent-infringement cases filed by Rambus against a collection of rival memory chipmakers that were scheduled to go to trial later this month. Judge Ronald M. Whyte of the U.S. District Court for the Northern District of California issued an order indefinitely postponing the long-running cases against Hynix Semiconductor, Micron Technology, Nanya Technology, and Samsung Electronics, pending appeals of earlier court decisions.
The lawsuits, which were filed in 2000 and scheduled to go to trial on February 17, allege that the defendants infringed Rambus patents in producing DDR DRAM–the most common type of memory in PCs today–as well as in making SDRAM and DDR2 DRAM. The vast majority of PCs and servers produced in the past several years use one of these types of memory, and variants of DDR are expected to be incorporated into PCs for the next several years.
