Description
The GS73024A is a high speed CMOS Static RAM organized
as 131,072 words by 24 bits. Static design eliminates the need
for external clocks or timing strobes. Operating on a single
3.3 V power supply, and all inputs and outputs are
TTL-compatible. The GS73024A is available in a 119-bump
BGA package.
