HM621100A Overview
The Hitachi HM621100A is a high speed 1M Static RAM organized as 1048576-word × 1bit. It realizes high speed access time (20/25/35 ns) and low power consumption, employing CMOS process technology and high speed circuit designing technology. It is most advantageous for the field where high speed and high density memory is required, such as the cache memory for main frame or 32-bit MPU.
