Description
The IDT71124 is a 1,048,576-bit high-speed static RAM orga-
nized 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 JEDEC
centerpower/GND pinout reduces noise generation and improves
system performance.
The IDT71124 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 IDT71124 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 IDT71124 is packaged in a 32-pin 400 mil Plastic SOJ.
