R0201-BS62LV1027
1. Stresses greater than those listed under ABSOLUTE
2. –2.0V in case of AC pulse width less than 30 ns.
SYMBOL
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.

These 17 address inputs select one of the 131,072 x 8-bit in the RAM
CE1 is active LOW and CE2 is active HIGH. Both chip enables must be active when
data read form or write to the device. If either chip enable is not active, the device is
deselected and is in standby power mode. The DQ pins will be in the high impedance
state when the device is deselected.
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.
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 impendence state when OE is inactive.
There 8 bi-directional ports are used to read data from or write data into the RAM.
