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.
