Description
The GM71C4403C is the new generation dynamic
RAM organized 1,048,576 words x 4 bit.
GM71C4403C has realized higher density, higher
performance and various functions by utilizing
advanced CMOS process technology. The
GM71C4403C offers Extended Data Out (EDO)
Mode as a high speed access Mode. Multiplexed
address inputs permit the GM71C4403C to be
packaged in a standard 300mil 20(26) pin plastic
SOJ , and standard 300mil 20(26) pin plastic TSOP
II. The package size provides high system bit
densities and is compatible with widely available
automated testing and insertion equipment. System
oriented features include single power supply of
5V+/-10% tolerance, direct interfacing capability
with high performance logic families such as
Schottky TTL.
