A lead-free metallic halide memristor is disclosed. The lead-free metallic halide memristor comprises a first electrode layer, an active layer and a second electrode layer, of which the active layer is made of a metallic halide material. Experimental data have proved that the lead-free metallic halide memristor possesses synaptic plasticity because of showing characteristics of short-term potentiation, short-term depression, long-term potentiation, long-term depression during the experiments. Therefore, the lead-free metallic halide memristor has significant potential for being used as an artificial synaptic element so as to be further applied in the manufacture of a reservoir computing chip. Moreover, experimental data have also proved that the lead-free metallic halide memristor also shows the characteristics of multi-level resistive switching, whereupon the lead-free metallic halide memristor can be further used as analog non-volatile memory so as to be further applied in the manufacture of a neuromorphic computing chip.
