High-Speed 16K x 9 Dual-Port Static RAM

Description
The IDT7016 is a high-speed 16K x 9 Dual-Port Static RAM. The
IDT7016 is designed to be used as stand-alone Dual-Port RAMs or as a
combination MASTER/SLAVE Dual-Port RAM for 18-bit-or-more wider
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 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 CMOS high-performance technology, these de-
vices typically operate on only 750mW of power.
The IDT7016 is packaged in a 64-pin PLCC.
