Description
The IDT71128 is a 1,048,576-bit high-speed static RAM
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 systemperformance.
The IDT71128 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 IDT71128 are TTL-compat-
ible and operation is froma single 5V supply. Fully static asyn-
chronous circuitry is used; no clocks or refreshes are required for
operation.
The IDT71128 is packaged in a 32-pin 400 ml Plastic SOJ.
