R1RP0408DI 4M High Speed SRAM

The R1RP0408DI is a 4-Mbit high speed static RAM organized 512-kword × 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 buf.
