Memory expansion is provided by an active LOW chip enable (En), an active LOW output enable (G), and three-state drivers.
This device has a power-down feature that reduces power consumption by more than 90% when deselected.
Writing to each memory is accomplished by taking chip enable (En) input LOW and write enable (Wn) inputs LOW.
Data on the eight I/O pins (DQ0 through DQ7) is then written into the location specified on the address pins (A0 through A18).
Reading from the device is accomplished by taking chip enable (En) and output enable (G) LOW while forcing write enable (Wn) HIGH.
Under these conditions, the contents of the memory location specified by the address pins will appear on the I/O pins.
The input/output pins are placed in a high impedance state when the device is deselected (En HIGH), the outputs are disabled (G HIGH), or during a write operation (En LOW and Wn LOW).
Perform 8, 16, 24 or 32 bit accesses by making Wn along with En a common input to any combination of the discrete memory die.
