描述
The R1RW0416D is a 4-Mbit High-Speed static RAM organized 256-kword × 16-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. Especially, LVersion and S-Version are low power consumption and it is the best for the battery backup system. The package prepares 400-mil 44-pin SOJ and 400-mil 44-pin plastic TSOPII for high density surface mounting.
