■ DESCRIPTION

The Fujitsu MB81P643287 is a CMOS Synchronous Dynamic Random Access Memory (SDRAM) with Fujitsu

advanced FCRAM (Fast Cycle Random Access Memory) Core Technology, containing 67,108,864 memory cells

accessible in an 32-bit format. The MB81P643287 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 MB81P643287 is designed to reduce the complexity of using a standard dynamic RAM

(DRAM) which requires many control signal timin.g constraints. The MB81P643287 uses Double Data Rate (DDR)

where data bandwidth is twice of fast speed compared with regular SDRAMs.

The MB81P643287 is ideally suited for Digital Visual Systems, 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 MB81P643287 adopts new I/O interface circuitry, SSTL_2 interface, which is capable of extremely fast data

transfer of quality under either terminated or point to point bus environment.
