zu den Lizenznehmern gehört. Das ist fast eine Monopolstellung.
Ich hab hier noch ein paar Infos von deren Webseite:
Rambus Inc. [Nasdaq:RMBS] develops and licenses high-performance, chip-to-chip interface technology that enables semiconductor memory devices 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, referred to as RDRAM(R), transfers data at speeds up to 800MHz over the Rambus Channel to Rambus-compatible ICs.
Rambus technology is an open standard, accessible to all semiconductor companies. Rambus provides licensees 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. In addition, the Rambus solution uses fewer ICs to deliver a given amount of performance and its low pin-count interface enables further component savings.
Rambus interface technology is broadly licensed to over 30 semiconductor companies which include the leading DRAM, ASIC and PC controller and chip set manufacturers. Eight of the world's top ten semiconductor companies license Rambus technology. For a complete list of Rambus licensees and infrastructure partners, visit our Partner Pavillion.
