Description

The Direct Rambus RIMM MC-4R256FKE8D is a general-purpose high-performance memory module subsystem suitable for use in a broad range of applications including computer memory, personal computers, workstations, and otherapplications where high bandwidth and low latency are required. MC-4R256FKE8D 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 SignalingLevel (RSL) technology permits 600MHz, 711MHz or 800MHz transfer rates while using conventional system and board design technologies.
Direct RDRAM MC-4R256FKE8D are capable of sustained data transfers at 1.25 ns per two bytes (10 ns per sixteenbytes).

The architecture of the Direct RDRAM MC-4R256FKE8D enables the highest sustained bandwidth for multiple, simultaneous,randomly addressed memory transactions. The separate control and data buses with independent rowand column control yield over 95 % bus efficiency. The Direct RDRAM's 32 banks support up to foursimultaneous transactions per device.
