A kind of memory technology, used exclusively by Intel, suitable for demanding applications. Its higher bandwidth makes it more efficient that SDRAM and very slightly faster than DDR (double data rate) RAM.
A new memory design for the P4 processors backed by Intell.
A high bandwidth DRAM, designed by Rambus, Inc. RDRAM is used mainly for video accelerators, and also in the Ultra 64 from Nintendo. It offers sustained transfer rates of around 1000 Mbps, compared to 200 Mbps for ordinary DRAM. Although it cannot be used as a direct replacement for existing memory, it is likely that it will replace DRAM and SDRAM as the main memory system in personal computers as the bus speeds required by these machines increase. SDRAM can operate up to around 100MHz, but RDRAM has been demonstrated by the manufacturers running at 600MHz.
DRAM architecture and a very high-speed data transfer technology
(1) Rambus, Inc. develops and licenses high-performance memory logic and circuit design technology and provides licensees with product design, layout, and testing information. (2) Direct Rambus is a high-speed memory technology that uses a narrow 16-bit bus (Rambus channel) to transmit data at speeds up to 800MHz. See Rambus Channel.
Rambus Incorporated (founded 1990) is a provider of high-speed interface technology, most notably their Rambus Dynamic RAM memory technology, which was intended to replace SDRAM and challenge DDR SDRAM as the standard memory used in computers.
