In an asymmetric Szilard engine model of Maxwell's demon, we show the
equivalence between information theoretical and thermodynamic entropies when
the demon erases information optimally. The work gain by the engine can be
exactly canceled out by the work necessary to reset demon's memory after
optimal data compression a la Shannon before the erasure.
