GENERAL DESCRIPTION
using a four-transistor memory cell with a high-speed, low-
power CMOS process. Micron SRAMs are fabricated using
double-layer metal, double-layer polysilicon technology.
for improved performance. For flexibility in high-speed
memory applications, Micron offers chip enable (? C / E ) and
output enable (? O / E ) with this organization. This enhancement
can place the outputs in High-Z for additional flexibility in
system design.

WITH SINGLE CHIP ENABLE,
REVOLUTIONARY PINOUT
enable (? W / E ) and ? C / E inputs are both LOW. Reading is
accomplished when ? W / E remains HIGH and ? C / E and ? O / E go
LOW. The device offers a reduced power standby mode
when disabled. This allows system designers to meet low
standby power requirements.
all inputs and outputs are fully TTL-compatible.
