GM71C(S)16400C/CL
4,194,304 WORDS x 4 BIT
CMOS DYNAMIC RAM
Description
Features
The GM71C(S)16400C/CL is the new
generation dynamic RAM organized 4,194,304
words x 4 bit. GM71C(S)16400C/CL has
realized higher density, higher performance and
various functions by utilizing advanced CMOS
process technology. The GM71C(S)16400C/CL
offers Fast Page Mode as a high speed access
mode. Multiplexed address inputs permit the
GM71C(S)16400C/CL to be packaged in a
standard 300 mil 24(26) pin SOJ, and a standard
300 mil 24(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 5V+/-10%
tolerance, direct interfacing capability with high
performance logic families such as Schottky
TTL.
