Stacked GeO/SrTiOx Resistive Memory with Ultralow Resistance Currents

Abstract

We report a high performance and low-power operated resistive memory. Using stacked covalent-bond-dielectric GeOx on metal-oxide SrTiOx to form the cost-effective Ni/GeOx/SrTiOx/TaN resistive random access memory, ultralow set power of small 1 mu W (0.9 mu A at 1.2 V), reset power of 13 pW (0.13 nA at 0.1 V), fast 50 ns switching time and good 10(6) cycling endurance are realized.
