The MT5LClOOl is organized as a 1,048,576 x 1 SRAM
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 flexibility in high-speed memory applications,
Micron offers chip enable (CE) capability. This enhance-
ment can place the outputs in High-Z for additional
flexibility in system design.
Writing to this device is accomplished when write enable
(WE) and CE inputs are both LOW. Reading is accom-

plished when WE remains HIGH while CE goes LOW. The
device offers a reduced power standby mode when dis-
abled. This allows system designers to meet low standby
The "LP" version provides a reduction in both CMOS
standby current (ISB2) and TTL standby current (ISB1) over
the standard part. This is achieved through the use of gated
inputs on the WE and address lines, which also facilitates
the design of battery-backed systems. That is, the gated
inputs simplify the design effort and circuitry required to
protect against inadvertent battery current drain during
power-down, when inputs may be at undefined levels.
All devices operate from a single +3.3V power supply
and all inputs and outputs are fully TTL-compatible and 5V
tolerant. These low-voltage parts are ideal for mixed 3.3V
and 5V systems.
