概要
説明
The R1RW0408D 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 buffer memory in system. The R1RW0408D is packaged in 400-mil 36-pin SOJ for high density surface mounting.
