Description
The R1RP0416D Series is a 4-Mbit high speed static RAM organized 256-k word × 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. It is packaged in 400-
mil 44-pin plastic SOJ and 400-mil 44-pin plastic TSOPII.
