CMOS DYNAMIC RAM
Description
Features
The GM71C(S)4100C/CL is the new generation
dynamic RAM organized 4,194,304 words x 1 bit.
GM71C(S)4100C/CL has realized higher density,
higher performance and various functions by
utilizing advanced CMOS process technology. The
GM71C(S)4100C/CL offers Fast Page Mode as a
high speed access Mode. Multiplexed address
inputs permit the GM71C(S)4100C/CL to the
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.
