Abstract
A memory comprising: a resistive-switching element having first and second electrodes separated by a layer of insulator; an energy storage component or load coupled to the resistive-switching element via a first switch; and a control circuit configured: to program the resistive-switching element to have a set state, wherein, in the set state, a filament forms a conducting path between the first and second electrodes; and, following a dissolution of the filament, to recover electrical energy, generated by the dissolution of the filament, from one of the first and second electrodes by activating the first switch.
