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. Writing is executed 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.
