Description

The 32-bit Direct Rambus RIMM module is a generalpurpose high-performance lines of memory modules suitable for use in a broad range of applications including computer memory, personal computers, workstations, and other applications where high bandwidth and latency are required.

The 32-bit RIMM module consists of 288Mb Direct Rambus DRAM (Direct RDRAM) devices. These are extremely high-speed CMOS DRAMs organized as 16M words by 18 bits. The use of Rambus Signaling Level (RSL) technology permits the use of conventional system and board design technologies. The 32-bit RIMM modules support 800MHz transfer rate per pin, resulting in total module bandwidth of 3.2GB/s.
