The MT5LC1008 is organized as a 131,072 x 8 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 dual chip enables (CE1, CE2). This enhance-
ment can place the outputs in High-Z for additional
flexibility in system design.
Writing to these devices is accomplished when write
enable (WE) and CE1 inputs are both LOW and CE2 is

HIGH. Reading is accomplished when WE and CE2 remain
HIGH and CE1 goes LOW. The device offers reduced
power standby modes when disabled. These modes allow
system designers to meetlow standbypowerrequirements.
The "LP" version provides a reduction in both CMOS
standby current (IsB2) and TTL standby current (ISBl) over
the standard part. This is achieved through the use of gated
inputs on the WE, OE and address lines. The gated inputs
also facilitate the design of battery-backed systems where
the designer needs to protect against inadvertent battery
current drain during power-down, when inputs may be at
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.
