IDT7034S/L
High-Speed 4K x 18 Dual-Port Static RAM
Description:
The IDT7034 is a high-speed 4K x 18 Dual-Port Static RAM. The
IDT7034 is designed to be used as a stand-alone 72K-bit Dual-Port
RAM or as a combination MASTER/SLAVE Dual-Port RAM for 36-bit
or more word systems. Using the IDT MASTER/SLAVE Dual-Port
RAM approach in 36-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 Chip Enable ( CE ) permits the on-chip circuitry of each
port to enter a very low standby power mode.
The IDT7034 utilizes a 18-bit wide data path to allow for parity at
the user's option. This feature is especially useful in data communica-
tion applications.
Fabricated using IDT’s CMOS high-performance technology, these
devices typically operate on only 850mW of power. Low-power (L)
versions offer battery backup data retention capability with typical
power consumption of 500μW from a 2V battery.
