GENERAL DESCRIPTION

The M21L216128A is a high speed, low power

asynchronous SRAM containing 2,097,152 bits and

organized as 131,072 by 16 bits, it is produced by high

performance CMOS process.

This device offers center power and ground pins for

improved performance and noise immunity. Static design

eliminates the need for external clocks or timing strobes. For

increased system flexibility and eliminating bus contention

problems, this device offers chip enable (

), separate byte

enable controls (

and

) and output enable (

) with this

organization.
