Description
The GS78116 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 GS78116 operates on a
single 3.3 V power supply and all inputs and outputs are TTL-
compatible. The GS78116 is available in 14 mm x 22 mm
BGA package.
