Abstract: Disclosed are a resistive random-access memory (ReRAM) based on resistive switching using a resistance-switchable conductive filler and a method for preparing the same. When a resistance-switchable conductive filler prepared by coating a conductive filler with a material whose resistance is changeable is mixed with a dielectric material, the dielectric material is given the resistive switching characteristics without losing its inherent properties. Therefore, various resistance-switchable materials having various properties can be prepared by mixing the resistance-switchable conductive filler with different dielectric materials. The resulting resistance-switchable material shows resistive switching characteristics comparable to those of the existing metal oxide film-based resistance-switchable materials. Accordingly, a ReRAM device having the inherent properties of a dielectric material can be prepared using the resistance-switchable conductive filler.
