Abstract

We report a stacked Y2O3/TiOx resistive random access memory (RRAM) device, showing good high-temperature switching characteristics of extremely low reset current of 1 μA at 150 °C, large off/on resistance window (>200) at 150 °C, large rectification ratio of ~300 at 150 °C and good current distribution at 85 °C. The good rectifying property, lower high-temperature sneak current and tighter high-temperature current distribution can be attributed to the combined results of the oxygen vacancies in TiOx and the related carrier depletion effect.
