STATIC RAM

Features

◆

PRELIMINARY

IDT7017L

◆

True Dual-Ported memory cells which allow simultaneous

reads of the same memory location

High-speed access

– Commercial: 15/20ns (max.)

– Industrial: 20ns (max.)

Low-power operation

– IDT7017L

Active: 1W (typ.)

Standby: 1mW (typ.)

Dual chip enables allow for depth expansion without

external logic

IDT7017 easily expands data bus width to 18 bits or

more using the Master/Slave select when cascading more
