GM76V256C Series
DESCRIPTION
The GM76V256C is a high-speed, low power and
32,786 X 8-bits CMOS Static Random Access
Memory fabricated using
Hyundai's high
performance CMOS process technology. It is
suitable for use in low voltage operation and
battery back-up application. This device has a
data retention mode that guarantees data to
remain valid at the minimum power supply
voltage of 2.0 volt.
