DESCRIPTION  
The Fujitsu MB81E643242 is a CMOS Synchronous Dynamic Random Access Memory (SDRAM) containing  
67,108,864 memorycellsaccessible in a 32-bit format. The MB81E643242 featuresa fullysynchronousoperation  
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 MB81E643242 is utilized using Fujitsu advanced FCRAM core technology and designed to improve the  
random access performance and the complexity of controlling reguler synchronous DRAM (SDRAM) which  
require many wait state due to long latency constraints.  
The MB81E643242 is ideally suited for embeded controllers, printers, file storage and other applications where  
a simple interface is needed.
