CMOS DYNAMIC RAM
LG Semicon Co.,Ltd.
Description
Pin Configuration
32 SOJ / TSOP II
The GM71V(S)65803A/AL is the new generation
dynamic RAM organized 8,388,608 words by 8bits.
The GM71V(S)65803A/AL utilizes advanced CMOS
Silicon Gate Process Technology as well as
advanced circuit techniques for wide operating
margins, both internally and to the system user.
System oriented features include single power supply
of 3.3V+/-10% tolerance, direct interfacing
capability with high performance logic families such
as Schottky TTL.
