... The chip enable input CE permits easy memory expansion with multiple-bank memory systems. When CE is High the device enters standby mode. The standard AS7C4098/AS7C34098 is guaranteed not to exceed 110/ 72mW power consumption in CMOS standby mode. A write cycle is accomplished by asserting write enable (WE) and chip enable (CE). Data on the input pins I/O1– ...
