The device has an automatic power-down feature, reducing the power consumption by more than 95% when deselected. An active LOW Write Enable signal WE controls the writing/reading operation of the memory. When CE and WE inputs are both LOW, data on the eight data input/output pins I/O0 through I/O7 is written into the memory location addressed by the address present on the address pins A0 through A14 . Reading the device is accomplished by selecting the device and enabling the outputs, CE and OE active LOW, while WE remains inactive or HIGH. Under these conditions, the contents of the location addressed by the information on address pins is present on the eight data input/output pins. The input/output pins remain in a high-impedance state unless the chip is selected, outputs are enabled, and Write Enable WE is HIGH.
