Description
The GS78116A is a high speed CMOS Static RAM organized
as 524,288-words by 16-bits. Static design eliminates the need
for external clocks or timing strobes. The GS78116A operates
on a single 3.3 V power supply, and all inputs and outputs are
TTL-compatible. The GS78116 is available in a
14 mm x 22 mm BGA package.
