The IDT7015 is a high-speed 8K x 9 Dual-Port Static RAMs. The IDT7015 is designed to be used as stand-alone Dual-Port RAM or as a combination MASTER/SLAVE Dual- Port RAM for 18-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-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 inmemory. 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 750mW of power.
The IDT7015 is packaged in a ceramic 68-pin PGA, a 64- pin PLCC and an 80-pin TQFP (Thin Quad FlatPack). Military grade product is manufactured in compliance with the latest revision of MIL-STD-883, Class B, making it ideally suited to military temperature applications demanding the highest level of performance and reliability.
