HY62UF8100 Series
128Kx8bit full CMOS SRAM
DESCRIPTION
The HY62UF8100 is a high speed, low power and
1M bit full CMOS SRAM organized as 131,072
words by 8bit. The HY62UF8100 uses high
performance full CMOS process technology and
designed for high speed low power circuit
technology. It is particularly 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 1.5V.
