MB81N643289-50

The Fujitsu MB81N643289-50 is a CMOS Fast Cycle Random Access Memory (FCRAM) containing 67,108,864 memory cells accessible in an 32-bit format. The MB81N643289-50 features a fully synchronous operation referenced to clock edge whereby all operations are synchronized at a clock input which enables high performance and simple user interface coexistence. The MB81N643289 is designed to reduce the complexity of using a standard dynamic RAM (DRAM) which requires many control signal timing constraints. The MB81N643289-50 uses Double Data Rate (DDR) where data bandwidth is twice of fast speed compared with regular SDRAMs.

The MB81N643289-50 is designed using Fujitsu advanced FCRAM Core Technology.

The MB81N643289-50 is ideally suited for Digital Visual System, High Performance Graphic Adapters, Hardware Accelerators, Buffers, and other applications where large memory density and high effective bandwidth are required and where a simple interface is needed.

The MB81N643289-50 adopts new I/O interface circuitry, 2.5 V CMOS Source Termination I/O interface, which is capable of extremely fast data transfer of quality under point to point bus environment.
