HM62864 - High Speed CMOS Static RAM

General Description

The Hitachi HM62864 is a CMOS static RAM organized 64-kword × 8-bit.

It realizes higher density, higher performance and low power consumption by employing 0.8 µm Hi-CMOS process technology.

It offers low power standby power dissipation; therefore, it is suitable for battery backup systems.

Key Features
