The GS72108A is a high speed CMOS Static RAM organized
as 262,144 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 TTLcompatible. The GS72108A is available in 400 mil SOJ and
400 mil TSOP Type-II packages.
