DATA SHEET 288M bits Direct Rambus DRAM for High Performance Solution µPD488588FF-C80-40 (512K words × 18 bits × 32s banks) Description The Direct Rambus DRAM (Direct RDRAM) is a general purpose high-performance memory device suitable for use in a broad range of applications including computer memory, graphics, video, and any other application where high bandwidth and low latency are required. The µPD488588FF is 288Mbits Direct Rambus DRAM (RDRAM), 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. Direct RDRAM devices are capable of sustained data transfers at 1.25ns per two bytes (10ns per sixteen bytes). The architecture of the Direct RDRAMs allows the highest sustained bandwidth for multiple, simultaneous randomly addressed memory transactions. The separate control and data buses with independent row and column control yield over 95% bus efficien...
