NOTES:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may
cause permanent damage to the device. This is a stress rating only and
functional operation of the device at these or any other conditions above those
indicated in the operational sections of this specification is not implied. Exposure
to absolute maximum rating conditions for extended periods may affect
reliability.
2. VTERM must not exceed Vcc + 10% for more than 25% of the cycle time or 10ns
maximum, and is limited to < 20mA for the period of VTERM > Vcc + 10%.

Description

The IDT7038L is a high-speed 64K x 18 Dual-Port Static RAM. The IDT7038 is designed to be used as a stand-alone 1152K-bit Dual-Port RAM or as a combination MASTER/SLAVE Dual-Port RAM for 36-bit-ormore word systems. Using the IDT MASTER/SLAVE Dual-Port RAM approach in 36-bit or wider memory system applications results in fullspeed, error-free operation without the need for additional discrete logic.

This IDT7038L 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 the chip enables (CE0 and CE1) permit the on-chip circuitry of each port to enter a very low standby power mode. Fabricated using IDT's CMOS high-performance technology, the IDT7038L typically operate on only1W of power. The IDT7038L is packaged in a 100-pin Thin Quad Flatpack (TQFP).
