Abstract
A resistive random access memory device is provided. The resistive random access memory device includes a first electrode, a second electrode, and an electrolyte layer disposed between the first electrode and the second electrode. One of the first electrode and the second electrode includes an ion supply layer providing two or more kinds of metal ions to the electrolyte layer. The two or more kinds of metal ions have different mobilities in the electrolyte layer. Two or more conductive bridges are generated by the two or more kinds of metal ions, respectively.
