1. Stresses greater than those listed under ABSOLUTE MAXIMUM
RATINGS may cause permanent damage to the device. This is a
stress rating only and functional operation of the device at these
or any other conditions above those indicated in the operational
sections of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
reliability.
1. This parameter is guaranteed and not tested.

Name
Function
A0-A14 Address Input
These 15 address inputs select one of the 32768 x 8-bit words in the RAM
CE Chip Enable Input
CE is active LOW. Chip enables must be active to read from or write to the device. If
chip enable is not active, the device is deselected and is in a standby power mode.
The DQ pins will be in the high impedance state when the device is deselected.
WE Write Enable Input
The write enable input is active LOW and controls read and write operations. With the
chip selected, when WE is HIGH and OE is LOW, output data will be present on the
DQ pins; when WE is LOW, the data present on the DQ pins will be written into the
selected memory location.
OE Output Enable Input
The output enable input is active LOW. If the output enable is active while the chip is
selected and the write enable is inactive, data will be present on the DQ pins and they
will be enabled. The DQ pins will be in the high impedance state when OE is inactive.
DQ0-DQ7 Data Input/Output
Ports
These 8 bi-directional ports are used to read data from or write data into the RAM.
