%X By modification of the electrode–solid-electrolyte interface with graphene, transit from valence change memories (VCM) to electrochemical metallization memories (ECM) in the cell Ta(C)/Ta2O5/Pt is demonstrated, thus, bridging both mechanisms. The ECM operation is discussed in the light of Ta-cation mobility in TaOx. The crucial role of electrochemical processes and moisture in the resistive switching process is also highlighted.
