Description
The GS78132A is a high speed CMOS Static RAM organized
as 262,144-words by 32-bits. Static design eliminates the need
for external clocks or timing strobes. The GS78132A operates
on a single 3.3 V power supply, and all inputs and outputs are
TTL-compatible. The GS78132A is available in a
14 mm x 22 mm BGA package.
