RIMM Memory

Question

Hello,

I have a question about a memory module called RIM memory...

Can you explain me what kind of memory that is?

I've never heard of it!

I know, it's a strange question, but I just like to know.

Greetings,

Stefan.

Not a problem In the world of computers, there are PLENTY of strange questions! Another name for RIMMs (Rambus Inline Memory Module)is Rambus DRAM.

Rambus DRAM

Rambus memory (RDRAM®) is a revolutionary step from SDRAM It's a new memory design with changes to the bus structure and how signals are carried Rambus memory sends less information on the data bus (which is 18 bits wide as opposed to the standard 32 or 64 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, to complete the circuit

Rambus DRAM modules are known as RIMMâ„¢ modules (Rambus inline memory modules) Rambus memory supports both ECC and non-ECC applications.
