DESCRIPTION  
The Fujitsu MB81F641642D is a CMOS Synchronous Dynamic Random Access Memory (SDRAM) containing  
67,108,864 memory cells accessible in a 16-bit format. The MB81F641642D features a fully synchronous oper-  
ation referenced to a positive edge clock whereby all operations are synchronized at a clock input which enables  
high performance and simple user interface coexistence. The MB81F641642D SDRAM is designed to reduce  
the complexity of using a standard dynamic RAM (DRAM) which requires many control signal timing constraints,  
and may improve data bandwidth of memory as much as 5 times more than a conventional DRAM.  
The MB81F641642D is ideally suited for workstations, personal computers, laser printers, high resolution graphic  
adapters/accelerators and other applications where an extremely large memory and bandwidth are required and  
where a simple interface is needed.
