Landauer's principle states that information erasure requires heat dissipation. Landauer's original result focused on equilibrium memories. We here investigate the reset of information stored in a nonequilibrium state of a symmetric two-state memory. We derive a nonequilibrium generalization of the erasure principle and demonstrate that the corresponding bounds on work and heat may be reduced to zero. We further introduce reset protocols that harness the initial preparation energy and entropyarXiv:1806.01034v1 fatcat:azqmkltc3fcqrpotjbt5x6qaxm
