Here we analyze asymmetric memory states to show that this energy cost can be shuffled around to any step in a write-erase cycle and need not accompany the logically irreversible step in a computation. We discuss the resulting symmetry between logically irreversible and reversible operations, along with the implications for resolutions of Maxwell's demon paradox.Statistical Mechanicstext
