(Nasdaq: RMBS - news) today announced that more than 100 Rambus(r)-based systems are available from leading PC and consumer products OEMs, double the number since the last survey conducted in April 2000. Rambus-based PC and consumer products are available from industry leaders such as Compaq, Dell, HP and Sony, powered by RDRAM(r) devices from Hyundai, Infineon, NEC, Samsung and Toshiba. Since the early 1990's systems designers and memory architects, representing a wide range of platforms and applications, realized the need for additional memory performance and bandwidth to support the anticipated increases in microprocessor frequency. These designers selected Rambus technology to eliminate the memory bottlenecks that would have negatively impacted system efficiency. Today, there are over 100 Rambus-based systems available including desktop PCs, workstations, consumer platforms as well as high performance, single and dual processor motherboards. RDRAM devices, with data rate transfers of up to 800MHz, enable a single Rambus Channel to achieve bandwidth of up to 1.6 gigabytes per second. Rambus technology allows architects the flexibility to incorporate multiple channels to scale memory capacity and bandwidth to meet system requirements. Intel 840 chipset-based personal computers and Sony's PlayStation(r)2 utilize two Rambus Channels for a total of 3.2 gigabytes per second of memory bandwidth. Rambus' architecture easily accommodates future performance enhancements due to its unique scalability. With Rambus technology, system designs can be optimized to meet the needs of a broad range of platforms including value PCs, desktops, workstations and servers, as well as digital televisions, set top boxes, networking products and game consoles. About Rambus Inc. Rambus Inc. develops and licenses high bandwidth chip connection technologies to enhance the performance of computers, consumer electronics and communications products. Current Rambus-based computers supported by Intel chipsets include Dell, Compaq, Hewlett-Packard, and IBM PCs and workstations. Sony's PlayStation(r)2 video game system uses Rambus memory. Providers of Rambus-based integrated circuits include the world's leading DRAM, ASIC and PC controller manufacturers. Currently, eight of the world's top-10 semiconductor companies license Rambus technology. More information on Rambus Inc. and its high bandwidth technologies is available at rambus.com .
