70V26S Overview
The IDT70V26 is a high-speed 16K x 16 Dual-Port Static RAM. The IDT70V26 is designed to be used as a stand-alone 256K-bit Dual-Port RAM or as a bination MASTER/SLAVE Dual-Port RAM for 32-bit-ormore 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.
70V26S Key Features
- True Dual-Ported memory cells which allow simultaneous reads of the same memory location
- High-speed access
- mercial: 25/35/55ns (max.)
- Low-power operation
- IDT70V26S Active: 300mW (typ.) Standby: 3.3mW (typ.)
- IDT70V26L Active: 300mW (typ.) Standby: 660μW (typ.)
- Separate upper-byte and lower-byte control for multiplexed bus patibility
- IDT70V26 easily expands data bus width to 32 bits or more using the Master/Slave select when cascading more than one dev
- M/S = VIH for BUSY output flag on Master M/S = VIL for BUSY input on Slave
- On-chip port arbitration logic
