Pin Descriptions
A
These 18 address inputs select one of the 256K x
16 bit segments in the RAM.
CE
CE
chip enables must be active to read from or write to
the device. If either chip enable is not active, the
device is deselected and is in a standby power
mode. The I/O pins will be in the high-impedance
state when deselected.
OE
The output enable input is active LOW. With the
chip enabled, when OE is Low and WE High, data
will be presented on the I/O pins. The I/O pins will
be in the high impedance state when OE is High.

Active low inputs. These inputs are used to enable
the upper or lower data byte.
WE
The write enable input is active LOW and controls
read and write operations. With the chip enabled,
when WE is HIGH and OE is LOW, output data will
be present at the I/O pins; when WE is LOW and
OE is HIGH, the data present on the I/O pins will be
written into the selected memory locations.
I/O
These 16 bidirectional ports are used to read data
from and write data into the RAM.
