HY63V8400 Series
512Kx8bit CMOS FAST SRAM
PRELIMINARY
DESCRIPTION
The HY63V8400 is a 4,194,304-bit high-speed
Static Random Access Memory organized as
524,288 words by 8-bits. The HY63V8400 uses
eight common input and output lines and has an
output enable pin which operates faster than.
address access time at read cycle. The device is
fabricated using Hyundai's advanced CMOS
process and designed for high-speed circuit
technology. It is particularly well suited for use in
high-density high-speed system applications
