I don't recognize it but from what I see of the board it is an EEPROM of some   
   sort or similar. If it has custom data in it of course the manufacturer can do   
   you no good.    
      
   If you got the gizmos and software you can access the data in it, but if it is   
   in question that data could be corrupt.    
      
   I do not believe it to be a MOSFET. It looks like pins 5-8 are all grounded   
   and they use the ones on the other side, like many eight pin EEPROMs. If it is   
   a MOSFET I can see the four pins to the ground plane for heat sinking, but the   
   other four, why four    
   ? You got gate, source and drain. All four of those pins have feedthroughs on   
   them.    
      
   Bottom line is I do not believe this to be a MOSFET, I believe it is an   
   EEPROM. If you have reason to believe I am wrong I am listening.
