PC Platform DRAM Technology Directions

PC Platform Evolution

Intel has a history of setting leadership directions in the adoption and support of a number of memory technologies (EDO, SDRAM) paving the way for faster, cheaper PC platforms. Looking into the future, memory bandwidth requirements keep increasing, driven by new PC platform applications and richer data types like 3D graphics and video.

Faster processors, the Accelerated Graphics Port, and faster serial buses are the platform ingredients driving the need for higher system memory bandwidth.

DRAM Technology Directions

• In the near term memory bandwidth requirements will be satisfied by EDO and 66 MHz SDRAM, transitioning to 100MHz in the 1998 timeframe

• Direct RDRAM technology is needed in the 1999 timeframe to further support PC applications that will provide interactive, lifelike experiences

• Intel and Rambus are working jointly on the development of Direct RDRAM technology by extending the existing Rambus technology:
  • Wider interface, higher clock rate and a more efficient protocol

  • The platform solution will include the DRAM interface, the Memory Controller Interface and the Interconnect

  • Rambus will transfer compatible designs to multiple vendors in the industry, as they have successfully done in the past

• Intel Architecture (IA) PC platform support for Direct RDRAM is targeted for 1999
