{{short description|Type of synchronous dynamic random-access memory}}
'''Rambus DRAM''' ('''RDRAM'''), and its successors '''Concurrent Rambus DRAM''' ('''CRDRAM''') and '''Direct Rambus DRAM''' ('''DRDRAM'''), are types of [[synchronous dynamic random-access memory]] (SDRAM) developed by [[Rambus]] from the 1990s 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. RDRAM is a serial [[memory bus]].

DRDRAM was initially expected to become the standard in [[computer memory|PC memory]], especially after [[Intel]] agreed to license the Rambus technology for use with its future chipsets. Further, DRDRAM was expected to become a standard for [[Video memory|graphics memory]]. However, RDRAM got embroiled in a [[standards war]] with an alternative technology&mdash;[[DDR SDRAM]]&mdash;and quickly lost out on grounds of price and, later, performance. By around 2003, DRDRAM was no longer supported in new personal computers.
