Abstract

We propose a selector-less Pr _0.7Ca _0.3MnO ₃ (PCMO) based resistive-switching RAM (RRAM) for high-density cross-point memory array applications. First, we investigate the inhomogeneous barrier with an effective barrier height (Φ _eff), i.e., self-formed Schottky barrier. In addition, a scalable 4F ² selector-less cross-point 1 kb RRAM array has been successfully fabricated, demonstrating set, reset, and read operation for high cell efficiency and high-density memory applications.
