General Description
The ACT-PS512K8 is a
Plastic High Speed, 4 Megabit
(4,194,304 bits) CMOS
Monolithic SRAM organized as
524,288 words by 8 bits.
Designed for high-speed, high
density, high reliablility, mass
memory and fast cache system
applications.
The plastic monolithic is
input and output TTL
compatible.Writingisexecuted
when the write enable (WE)
and chip enable (CE) inputs are
low. Reading is accomplished
when WE is high and CE and
output enable (OE) are both
low. Access time grades of
10ns 12ns, 15ns, 17ns, 20ns
and 25ns are standard.
