GM71V65163A GM71VS65163AL
4,196,304 WORDS x 16 BIT CMOS DYNAMIC RAM
Description
The GM71V(S)65163A/AL is the new generation dynamic RAM organized 4,196,304 words by 16 bits. The GM71V(S)65163A/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. The GM71V(S)65163A/AL offers Extended Data Out(EDO) Mode as a high speed access mode.
