IDT7019L

High-Speed 128K x 9 Dual-Port Static RAM

Industrial and Commercial Temperature Ranges

Description

The IDT7019 is a high-speed 128K x 9 Dual-Port Static RAM. The

IDT7019 is designed to be used as a stand-alone 1152K-bit Dual-Port

RAMorasacombinationMASTER/SLAVEDual-PortRAMfor18-bit-or-

more word systems. Using the IDT MASTER/SLAVE Dual-Port RAM

approach in 18-bit or wider memory system applications results in full-

speed,error-freeoperationwithouttheneedforadditionaldiscretelogic.

This device provides two independent ports with separate control,

address,andI/Opinsthatpermitindependent,asynchronousaccessfor

reads or writes to any location in memory. An automatic power down

circuitry of each port to enter a very low standby power mode.

Fabricated using CMOS high-performance technology, these de-

vices typically operate on only1W of power.
