Description
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.
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 a 1,048,576-bit high-speed static RAM orga-
