Rambus memory technology is a proprietary memory technology invented by Rambus Inc. Due to increasing memory bandwidth requirements, the Intel
® Corporation selected Rambus to power a generation of high-performance PCs. Rambus memory chips are called RDRAMs (for Rambus DRAMs). Rambus memory modules, called RIMM™ modules, are used on PCs with Intel chipsets supporting Rambus memory.
RDRAM is considered to be a revolutionary memory technology, as opposed to evolutionary, when compared to SDRAM because it requires a totally new memory architecture. Rambus memory socket in a motherboard must be populated for the memory to work correctly, Continuity RIMM (C-RIMM) and Continuity Small-Outline RIMM (C-SORIMM) modules are required to maintain the continuity of the signals. C-RIMM and C-SORIMM modules are especially-made chipless RIMM modules.
