... The chip enable input CE permits easy memory expansion with multiple-bank memory systems. When CE is high the device enters standby mode. The AS7C4096 is guaranteed not to exceed 110 mW power consumption in CMOS standby mode. Both devices offer 2.0V data retention. A write cycle is accomplished by asserting write enable (WE) and chip enable (CE). Data on the input pins I/O1–I/O8 is written on the rising edge of WE (write cycle (write cycle 2) ...
