DESCRIPTION

The M48Z35/35Y ZEROPOWER RAM is a 32

Kbit x8 non-volatile static RAM that integrates

power-fail deselect circuitry and battery control

logic on a single die. The monolithic chip is avail-

able in two special packages to provide a highly in-

tegrated battery backed-up memory solution.
