The IDT70T24L is a high-speed 8/4K x 18 (8/4K x 16) Dual-Port Static RAM. The IDT70T24L is designed to be used as a stand-alone Dual-Port RAM or as a combination MASTER/SLAVE Dual-Port RAM for 36-bit (32-bit) or wider memory system applications results in full-speed, error-free operation without the need for additional discrete logic.

This device provides two independent ports with separate control, address, and I/O pins that permit independent, asynchronous access for reads or writes to any location in memory. An automatic power down feature controlled by CE permits the on-chip circuitry of each port to enter a very low standby power mode.

Fabricated using IDT's CMOS high-performance technology, these devices typically operate on only 200mW of power.

The IDT70T24L is packaged in a plastic 100-pin Thin Quad Flatpack and a 100-pin fine pitch Ball Grid Array.
