HY628100A Series
128Kx8bit CMOS SRAM
DESCRIPTION
The HY628100A is a high speed, low power and
1M bit CMOS Static Random Access Memory
organized as 131,072 words by 8bit. The
HY628100A uses high performance CMOS
process technology and designed for high speed
low power circuit technology. It is particulary well
suited for used in high density low power system
application. This device has a data retention
mode that guarantees data to remain valid at a
minimum power supply voltage of 2.0V.
