  • Abstract
    We report a novel nonvolatile resistive switching memory with a Cu/Ta2O5/TiN structure. This memory device has low power (100 muA/1.5 V), large threshold voltage of 0.8 V, moderate endurance of 102 cycles, and excellent retention with high resistance ratio of 2.4times102 after 105 s (26 hours). Furthermore, the threshold voltage can be increased by both the thickness of Ta2O5 solid electrolyte and annealing temperatures, which can make easier to design the memory circuit.
