128K X 16 LOW POWER
CMOS STATIC RAM
GENERAL DESCRIPTION
The T15V2M16B is a very Low Power CMOS
Static RAM organized as 131,072 words by 16
bits
.
This
device
is
fabricated by high
performance CMOS technology. It can be operated
under wide power supply voltage range from
+2.7V to +3.6V.
The T15V2M16B inputs and three-state
outputs are TTL compatible and allow for direct
interfacing with common system bus structures.
Data retention is guaranteed at a power supply
voltage as low as 2V.
