Product Summary
The IDT7025S55PF is a high-speed 8K x 16 Dual-Port Static RAM. The IDT7025S55PF is designed to be used as a stand-alone 128K-bit Dual-Port RAM or as a combination MASTER/SLAVE Dual-Port RAM for 32-bit or more word systems. Using the IDT MASTER/SLAVE Dual-Port RAM approach in 32-bit or wider memory system applications results in fullspeed, error-free operation without the need for additional discrete logic.
