CMOS DYNAMIC RAM
Description
Features
The GM71C(S)17803C/CL is the new
generation dynamic RAM organized 2,097,152
x 8 bit. GM71C(S)17803C/CL has realized
higher density, higher performance and various
functions by utilizing advanced CMOS process
technology. The GM71C(S)17803C/CL offers
Extended Data out(EDO) Page Mode as a high
speed access mode. Multiplexed address inputs
permit the GM71C(S)17803C/CL to be
packaged in standard 400 mil 28 pin plastic
SOJ, and standard 400mil 28pin plastic TSOP
II. The package size provides high system bit
densities and is compatible with widely
available automated testing and insertion
equipment.
