Description
The IDT7025 is a high-speed 8K x 16 Dual-Port Static RAM. The IDT7025 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 full-speed, errorfree operation without the need for additional discrete logic.
Features
◆ True Dual-Ported memory cells which allow simultaneous
reads of the same memory location
◆ High-speed access

Active: 750mW (typ.)
Standby: 5mW (typ.)
– IDT7025L
Active: 750mW (typ.)
Standby: 1mW (typ.)
◆ Separate upper-byte and lower-byte control for multiplexed
bus compatibility
◆ IDT7025 easily expands data bus width to 32 bits or more
using the Master/Slave select when cascading more than
one device
◆ M/S = H for BUSY output flag on Master
M/S = L for BUSY input on Slave
◆ Interrupt Flag
◆ On-chip port arbitration logic
◆ Full on-chip hardware support of semaphore signaling
between ports
◆ Fully asynchronous operation from either port
◆ Battery backup operation—2V data retention
