IDT70V26S/L
High-Speed 16K x 16 Dual-Port Static RAM
Description
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 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, 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 in memory. 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 300mW of power.
The IDT70V26 is packaged in a ceramic 84-pin PGA and
84-Pin PLCC.
