GENERAL DESCRIPTION
The T15M1024A is a very Low Power CMOS
Static RAM organized as 131,072 words by 8 bits.
That operates on a wide voltage range from +5V
(±10%) power supply, Fabricated using high
performance CMOS technology, 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 1.5V.
