Rambus Memory

"Rambus DRAM(short as RDRAM), a type of memory (DRAM) developed by Rambus, Inc. Whereas the fastest current memory technologies used by PCs (SDRAM) can deliver data at a maximum speed of about 100 MHz and 133 MHz Rambus Memory RDRAM transfers data at up to 800 MHz. As of late 1999, Intel has been using RDRAM memory in its Pentium III Xeon processors and later in its Pentium 4 processors. Intel and Rambus are also had a newer version of RDRAM, that supports data transfer speeds at up to 1,600 MHz." (www.webopedia.com)

Rambus memory (RDRAM®) is a revolutionary step from SDRAM. It's a memory design with changes to the bus structure and how signals are carried. Rambus memory sends less information on the data bus (which is 16 or 18 bits wide as opposed to the standard 64 or 72 bits) but it sends data more frequently. It also reads data on both the rising and falling edges of the clock signal, as DDR does. As a result, Rambus memory is able to achieve effective data transfer speeds of 800MHz and higher.

Another difference with Rambus memory is that all memory slots in the motherboard must be populated. Even if all the memory is contained in a single module, the "unused" sockets must be populated with a PCB, known as a continuity module (CRIMM), to complete the circuit.

Rambus memory supports both ECC and non-ECC applications.

Allmemoryupgrades.com offers Rambus memory modules in capacities up to 512MB.

Memory Knowledgebase:

Memory types like SDRAM, DDR, and Rambus RDRAM are found in most of today's computer memory applications:

• RDRAM - Rambus Dynamic Random Access Memory;
• DRAM - Dynamic Random Access Memory;
• RAM - Random Access Memory;
• DIMM - Dual in-line Memory Module. This physical property describes a module with signal and power pins on both sides of the board. DIMMs can be any number of pins including 144pin SODIMM SDRAM, 168pin SDRAM memory, and 184pin DDR SDRAM.
• ECC - Error Correcting Code. Logic designed to detect and correct memory errors. Memory modules designed with 72 bits of memory support the motherboard's ECC function.
