In the unipolar mode, two different current limits must be used so that during the creation of a conductive path/filament by [V.sub.SET] a low current compliance limit [CC.sub.SET] would enable a controlled formation of these conductive paths, while a higher current compliance limit [CC.sub.RESET] would be required for the dissolution of this conductive path/filament by [V.sub.RESET] (much like the breakdown of a fuse after passing a large current density through it).
