PRELIMINARY DATA SHEET MOS INTEGRATED CIRCUIT MC-4R256CEE6B, 4R256CEE6C Direct RambusTM DRAM RIMMTM Module 256M-BYTE (128M-WORD x 16-BIT) Description The Direct Rambus RIMM module 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 other applications where high bandwidth and low latency are required. MC-4R256CEE6B, 4R256CEE6C modules consists of sixteen 128M Direct Rambus DRAM (Direct RDRAM™) devices (µPD488448). These are extremely high-speed CMOS DRAMs organized as 8M words by 16 bits. The use of Rambus Signaling Level (RSL) technology permits 600MHz, 711MHz or 800MHz transfer rates while using conventional system and board design technologies.
