IDT71128

CMOS Static RAM 1 Meg (256K x 4-Bit) Revolutionary Pinout Features x x IDT71128 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-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 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-compatible and operation is from a single 5V supply. Fully static asynchronous circuitry is used; no clocks or refreshes are required for operation. The IDT71128 is packaged in a 32-pin 400 mil Plastic SOJ. x x x x x 256K x 4 advanced high-speed CMOS static RAM JEDEC revolutionary pinout (center power/GND) for reduced noise.
