Description
The GS78108A is a high speed CMOS Static RAM organized
as 1,048,576-words by 8-bits. Static design eliminates the need
for external clocks or timing strobes. The GS78108operates on
a single 3.3 V power supply, and all inputs and outputs are
TTL-compatible. The GS7810A8 is available in a
14 mm x 22 mm BGA package.
