Description
The GM71C(S)4400C/CL is the new generation
dynamic RAM organized 1,048,576 words x 4 bit.
GM71C(S)4400C/CL has realized higher density,
higher performance and various functions by
utilizing advanced CMOS process technology. The
GM71C(S)4400C/CL offers Fast Page Mode as a
high speed access Mode. Multiplexed address
inputs permit the GM71C(S)4400C/CL 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.
