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 (
CE
), separate byte
enable controls (
LB
and
HE
) and output enable (
OE
) with this
organization.
