DESCRIPTION  
The Fujitsu MB81N26847A/261647A is a CMOS Fast Cycle Random Access Memory (FCRAM) containing  
268,435,456 memory cells accessible in an 8-bit or 16-bit format. The MB81N26847A/261647A 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 MB81N26847A/261647A is designed to  
reduce the complexity of using a standard Dynamic RAM (DRAM) which requires many control signal timing  
constraints. The MB81N26847A/261647A uses Double Data Rate (DDR) where data bandwidth is twice of fast  
speed compared with regular SDRAMs.  
The MB81N26847A/261647A is designed using Fujitsu advanced FCRAM Core Technology.  
The MB81N26847A/261647A is ideally suited for Enterprise Servers, Network Systems, Hardware Accelerators,  
Buffers, and other applications where large memory density and high effective bandwidth are required and where  
a simple interface is needed.  
The MB81N26847A/261647A adopts CMOS I/O interface circuitry, 2.5 V Half-strength SSTL-2 interface, which  
is capable of extremely fast data transfer of quality.
