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 operates on a
single 3.3 V power supply and all inputs and outputs are TTL-
compatible. The GS71108A is available in a 6 mm x 8 mm
Fine Pitch BGA package, as well as in 300 mil and 400 mil
SOJ and 400 mil TSOP Type-II packages.
