HY628400 Series
512Kx8bit CMOS SRAM
DESCRIPTION
The HY628400 is a high-speed, low power and
4M bits CMOS SRAM organized as 524,288
words by 8 bits. The HY628400 uses Hyundai's
high performance twin tub CMOS process
technology and was designed for high-speed and
low power circuit technology. It is particulary 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.
