Rambus DRAM (
RDRAM'), and its successors
Concurrent Rambus DRAM (
CRDRAM) and
Direct Rambus DRAM (
DRDRAM), are types of synchronous
dynamic RAM developed by
Rambus from the late-1980s through to the early-2000s. The third-generation of Rambus DRAM, DRDRAM was replaced by
XDR DRAM. Rambus DRAM was developed for high-bandwidth applications, and was positioned by Rambus as replacement for various types of contemporary memories, such as
SDRAM.
