GENERAL DESCRIPTION
The MT5C1009 is a 1,048,576-bit high-speed CMOS
static RAM organized as 131,072 words by 8 bits. This device
uses 8 common input and output lines and has an output en-
able pin which operate faster than address access times during
READ cycle.
For design flexibility in high-speed memory applica-
tions, this device offers chip enable (CE\) and output enable
(OE\) features. These enhancements can place the outputs in
High-Z for additional flexibility in system design.
Writing to these devices is accomplished when write
enable (WE\) and CE\ inputs are both LOW. Reading is ac-
complished when WE\ remains HIGH and CE\ and OE\ go
LOW. The devices offer a reduced power standby mode when
disabled, allowing system designs to achieve low standby power
requirements.
The “L” version offers a 2V data retention mode,
reducing current consumption to 2mW maximum.
All devices operate from a single +5V power supply
and all inputs and outputs are fully TTL compatible. It is par-
ticularly well suited for use in high-density, high-speed system
applications.

*Stresses at or greater than those listed under “Absolute Maxi-
mum Ratings” may cause permanent damage to the device.
This is a stress rating only and functional operation of the device
at these or any other conditions above those indicated in the
operation section of this specification is not implied. Exposure
to absolute maximum rating conditions for extended periods
will affect reliability. Refer to page 17 of this datasheet for a
technical note on this subject.
** Junction temperature depends upon package type, cycle time,
loading, ambient temperature and airflow, and humidity.
