Description
The R1RP0408DI Series is a 4-Mbit high speed static RAM organized 512-k word × 8-bit. It has realized
high speed access time by employing CMOS process (6-transistor memory cell) and high speed circuit
designing technology. It is most appropriate for the application which requires high speed, high density
memory and wide bit width configuration, such as cache and buffer memory in system. It is packaged in
400-mil 36-pin plastic SOJ.
