HM624256A Series 262144-word × 4-bit High Speed CMOS Static RAM Rev. 0.0 Dec. 1, 1995 Description The Hitachi HM624256A is a high speed 1M Static RAM organized as 262,144-word × 4-bit. 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. The HM624256A, packaged in a 400-mil plastic SOJ is available for high density mounting.
