  Motivated by the recent work by Mandal and Jarzynski on autonomous Maxwell
demon information engine, we have extended their model by introducing two
different heat baths. The system (demon) is coupled to a memory register (tape)
and a work source. The performance of the system depends on the interplay
between these two sources along with the heat baths.
  We have found the system can act as an engine, refrigerator or an eraser.
Even the combination of any two is possible in some parameter space. We have
achieved the efficiency of the engine is greater than Carnot limit. The
coefficient of performance of refrigerator also achieves larger than Carnot
limit.
