Abstract

A resistive random access memory (RRAM) device is provided. The RRAM includes: a bottom electrode via disposed in a first dielectric layer; a bottom electrode electrically connected to the bottom electrode via and protruding upwardly from the bottom electrode via in a vertical direction, wherein the bottom electrode has a tapered shape and includes a base portion extending upwardly from a bottom surface to an interface and a tip portion extending upwardly from the interface to a top surface; a top electrode disposed in a second dielectric layer, the top electrode distanced above and vertically aligned with the bottom electrode; and a switching layer disposed between the first dielectric layer and the second dielectric layer, the switching layer enclosing the bottom electrode, wherein a conductive path between the bottom electrode and the top electrode is formed when a forming voltage is applied.
