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.
Features
Single 5 V supply and high density 28-pin package (DIP and SOJ)
High speed
Access time: 20/25/35 ns (max)
Low power dissipation
Active mode: 350 mW (typ)
Standby mode: 100 µW (typ)
Completely static memory
No clock or timing strobe required
Equal access and cycle time
Directly TTL compatible
All inputs and outputs
