a Schematic diagram exhibiting a biological synapse. b I-V curves of the ZnPS3 memristor for 50 consecutive sweeps. c, d Statistical analysis of the set voltage Vset and reset voltage Vreset (c), and on/off ratio (d). e Comparison of the operating voltages of the ZnPS3 memristor in non-volatile switching mode with those of non-volatile memristors based on other two-dimensional materials and oxides, indicating the low switching voltages of the ZnPS3 memristor. Detailed references are provided in Supplementary Table 4. f Multi-level conductence. g Long-term plasticity of LTP and LTD stimulated by pulse train with varying pulse amplitude for 20 consecutive cycles.
