1,048,576 WORDS x 16 BIT
CMOS DYNAMIC RAM
Description
Features
The GM71C(S)18163C/CL is the new
generation dynamic RAM organized 1,048,576
x 16 bit. GM71C(S)18163C/CL has realized
higher density, higher performance and various
functions by utilizing advanced CMOS process
technology. The GM71C(S)18163C/CL offers
Extended Data out(EDO) Mode as a high speed
access mode. Multiplexed address inputs permit
the GM71C(S)18163C/CL to be packaged in
standard 400 mil 42pin plastic SOJ, and standard
400mil 44(50)pin plastic TSOP II. The package
size provides high system bit densities and is
compatible with widely available automated
testing and insertion equipment.
