A resistive random access memory (RRAM) devices and resistive random access memory (RRAM) arrays are provided, the RRAM devices include a first electrode layer, a variable resistance material layer formed of an oxide of a metallic material having a plurality of oxidation states, an intermediate electrode layer on the variable resistance material layer and formed of a conductive material having a lower reactivity with oxygen than the metallic material, and a second electrode layer on the intermediate electrode layer. The RRAM arrays include at least one of the aforementioned RRAM devices.
