Description

The Direct Rambus SO-RIMM module is a general-purpose high-performance memory module subsystem suitable for use in a broad range of applications including computer memory, mobile personal computers, networking systems, and other applications where high bandwidth and low latency are required.

MC-4R256FKE8S modules consists of eight 288M Direct Rambus DRAM (Direct RDRAM) devices (µPD488588). These are extremely high-speed CMOS DRAMs organized as 16M words by 18 bits. The use of Rambus Signaling Level (RSL) technology permits 800MHz transfer rates while using conventional system and board design technologies.

Features
