HY628400A Series
DESCRIPTION
The HY628400A is a high-speed, low power and
4M bits CMOS SRAM organized as 512K words
by 8 bits. The HY628400A uses Hynix's high
performance twin tub CMOS process technology
and was designed for high-speed and low power
circuit technology. It is particularly well suited for
use in high-density and low power system
applications. This device has a data retention
mode that guarantees data to remain valid at the
minimum power supply voltage of 2.0V.
