DESCRIPTION:
The IDT71024 is a 1,048,576-bit high-speed static RAM
organized as 128K x 8. It is fabricated using IDT’s high-
performance, high-reliability CMOS technology. This state-
of-the-art technology, combined with innovative circuit design
techniques, provides a cost-effective solution for high-speed
memory needs.
The IDT71024 has an output enable pin which operates as
fast as 6ns, with address access times as fast as 12ns
available. All bidirectional inputs and outputs of the IDT71024
are TTL-compatible and operation is from a single 5V supply.
Fully static asynchronous circuitry is used; no clocks or
refreshes are required for operation.
The IDT71024 is packaged in 32-pin 300 mil Plastic SOJ,
32-pin 400 mil Plastic SOJ, and 32-pin 400 x 820 mil LCC
packages.
