Rambus Inc. [Nasdaq:RMBS] develops and licenses scalable bandwidth, chip-to-chip interface technologies that enables semiconductor memory devices and ASICs to keep pace with faster generations of processors and controllers. Rambus technology is incorporated onto dynamic-random-access-memory (DRAM) chips and the logic devices that control them to deliver more than ten times the performance of conventional DRAMs. A single Rambus(R) DRAM device, referred to as an RDRAM(R) device, transfers data at speeds up to 800MHz and beyond over the Rambus Channel to Rambus-compatible ICs.
Rambus chip connection technology is an open standard, accessible to all semiconductor companies. Rambus provides licensees with a full range of design, documentation and system-engineering services. In exchange, IC companies pay an up-front license fee and royalties. System companies buy Rambus-compatible ICs from licensed semiconductor companies; they do not pay separate royalties or license fees for using Rambus technology.
The high-bandwidth, low pin-count Rambus interface has a major impact on improving the price/performance and reducing the size of a broad range of systems from desktop computers to portables to communications systems to multimedia and consumer digital video products. Rambus Inc.'s unique technology uses standard CMOS processes, low cost IC packaging, and standard printed circuit board technologies to deliver the highest performance at a low cost.
