To meet the requirements of flexible memory applications, we have compared two capping layers of GeOx and AlOx on a TiOy resistive random access memory (RRAM) at room temperature. A Ni/GeO x/TiOy/TaN RRAM shows a large resistance window of >102, 85 °C retention, a highresistance-state (HRS) activation energy (Ea) of 0.52 eV, and a good DC cycling of 103 cycles, which are significantly better than those of a Ni/ AlO x/TiOy/TaN RRAM, which has a high-defect-density dielectric of AlOx.
