organized as 256K x 4. It is fabricated using IDT’s high-perfor-
mance, 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 IDT71128 are TTL-compat-
ible and operation is from a single 5V supply. Fully static asyn-
chronous circuitry is used; no clocks or refreshes are required for
operation.
The IDT71128 is a 1,048,576-bit high-speed static RAM
The IDT71128 has an output enable pin which operates as fast
The IDT71128 is packaged in a 32-pin 400 mil Plastic SOJ.
