The MT5C1M4B2 is organized as a 1,048,576 x 4 SRAM
using a four-transistor memory celCwith a high-speed,
low-power CMOS process. Micron 4 Meg SRAMs are fab-
ricated using double-layer metal, triple-layer polysilicon
This device offers multiple center power and ground pins
for improved performance. For flexibility in high-speed
memory applications, Micron offers chip enable (CE) and
output enable (OE) with this configuration. These enhance-
ments can place the outputs in High-Z for additional flex-
ibility in system design.

WITH OUTPUT ENABLE
PIN ASSIGNMENT (Top View)
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 output enable (OE)
and CE go LOW. The device offers a reduced power stand-
by mode when disabled. This allows system designers to
meet low standby power requirements.
The "P" version provides a 90 percent reduction in TIL
standby current (ISB1) through the use of gated inputs on the
WE, OE 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
inputs may be at undefined levels.
All devices operate from a single +5V power supply and
all inputs and outputs are fully TTL-compatible.
