1. A heat mitigated bipolar resistive switch comprising: a bipolar resistive switching (BRS) matrix sandwiched between a first electrode and a second electrode, the BRS matrix to support bipolar switching of a conduction channel formed between the first and second electrodes through BRS matrix; and a heat mitigator to reduce heat in the BRS matrix generated during the bipolar switching, the heat mitigator comprising one or both of a parallel-connected NDR element to limit current flowing in the BRS matrix and a high thermal conductivity material to conduct the generated heat away from the BRS matrix above a predetermined elevated temperature, wherein the parallel-connected NDR element comprises an S-NDR material, the parallel-connected NDR element being connected in parallel with the conduction channel of the BRS matrix between the first and second electrodes to provide a shunt current path that bypasses the BRS matrix.
