Description
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, L-Version 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.
