4M High-Speed SRAM (512-kword × 8-bit)

The R1RP0408D Series is a 4Mbit high-speed static RAM organized 512-k word × 8-bit. It realizes high-speed access time by employing the CMOS process (6-transistor memory cell) and high-speed circuit design technology. It is most appropriate for applications that require high-speed, high-density memory and a wide bit width configuration, such as cache and buffer memory in systems. It is packaged in a 400-mil 36-pin plastic SOJ.
