Rambus to Showcase High-Speed Memory Technologies and Architectures at IDF 2008

Who: Rambus Inc. (Nasdaq: RMBS) Where: Intel Developer Forum Moscone Center West 800 Howard Street San Francisco, CA Booth #712 When: August 19-21, 2008

Join Rambus at Intel Developer Forum 2008 for demos and displays of Rambus' latest technology developments:

-- The Terabyte Bandwidth Initiative, featuring new memory signaling innovations that facilitate data rates of 16Gbps, enables a future memory architecture that can deliver an unprecedented Terabyte per second (TB/s) of memory bandwidth (1 terabyte = 1,024 gigabytes) to a single System-on-Chip (SoC). Innovations include the industry's first differential signaling for both data and command/address (C/A); FlexLink(TM) C/A, the industry's first full-speed, point-to-point C/A link; and 32X Data Rate technology (32 data bits per input clock cycle).

-- Low power signaling technology operating at 6.25Gbps with a power-performance metric of 2.2mW/Gbps.

-- PLAYSTATION(R)3 (PS3(TM)) open demo board, featuring the XDR(TM) memory architecture. The Rambus XDR memory interface and FlexIO(TM) processor bus on the Cell Broadband Engine(TM) enable an unprecedented aggregate bandwidth of over 65GB/s in the PS3.

-- TI DLP(R) projector open demo board, featuring the XDR memory architecture. This architecture, including XDR DRAM , XDR memory controller (XMC), XDR IO cell (XIO), and XDR clock generator (XCG), delivers memory bandwidth up to 8.0GB/s in the latest generation of HD front projectors.
