Description
The GS71108A is a high speed CMOS Static RAM organized
as 131,072 words by 8 bits. Static design eliminates the need
for external clocks or timing strobes. The GS 71108 operates
on a single 3.3 V power supply and all inputs and outputs are
TTL-compatible. The GS71108A is available in the 6 mm x 8
mm Fine Pitch BGA package.
