R1RP0404D Overview
The R1RP0404D is a 4-Mbit high speed static RAM organized 1-Mword × 4-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 and high density memory, such as cache and buffer memory in system.
