Rambus makes run at SDRAM with modules

LAS VEGAS—At the Comdex trade show, an official of Rambus Inc. of Mountain View,
Calif., predicted the high-speed Rambus memory interface will eclipse synchronous dynamic
RAM by 2000.

Julia A. Cates, Rambus’ product marketing manager, said about 500 64M Rambus
modules have gone to Dell Computer Corp. for evaluation and prototyping. Each module
consists of 16 64M error-correcting chips made by LG Semicon America Inc. of San Jose,
Calif., on a circuit board from Kingston Technology Co. of Fountain Valley, Calif.

Rambus has licensed its technology to several chip and module manufacturers. Intel
Corp. and Advanced Micro Devices Inc. of Sunnyvale, Calif., both have announced plans to
incorporate Rambus into their next-generation memory controller chip sets and
motherboards. Rambus modules, also called RIMMs, have the same form factor as double
in-line memory modules.

Cates said future 400-MHz PC buses could exploit Rambus to reach memory throughput of
1.6G per second.
