摘要: A heat mitigated bipolar resistive switch includes a BRS matrix sandwiched between first and second electrodes and a heat mitigator. The BRS matrix is to support bipolar switching of a conduction channel formed between the first and second electrodes through BRS matrix. The heat mitigator is to reduce heat in the BRS matrix generated during bipolar switching. The heat mitigator includes 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.
