The MT5C1005 is organized as a 262,144 x 4 SRAM using
a four-transistor memory cell with a high-speed, low-power
CMOS process. MicronSRAMs are fabricated using double-
layer metal, double-layer polysilicontechnology.
For flexibility in high-speed memory applications,
Micron offers chip enable (CE) and output enable (OE) with
this organization. This enhancement 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 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 "L" and "LP" versions each provide a 70 percent
reduction in CMOS standby current (IsB2) over the standard
version. The LP version also provides a 90 percent reduc-
tion in TTL standby current (ISB1) through the use of gated
inputs on the WE, OE and address lines, which also facili-
tates the design ofbattery 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 +5V power supply and
all inputs and outputs are fully TIL-compatible.
