Abstract

To improve the operation current lowing of the Zr:SiO2 RRAM devices, a space electric field concentrated effect established by the porous SiO2 buffer layer was investigated and found in this study. The resistive switching properties of the low-resistance state LRS and high-resistance state HRS in resistive random access memory RRAM devices for the single-layer Zr:SiO2 and bilayer Zr:SiO2-porous SiO2 thin films were analyzed and discussed. In addition, the original space charge limited current SCLC conduction mechanism in LRS and HRS of the RRAM devices using bilayer Zr:SiO2-porous SiO2 thin films was found. Finally, a space electric field concentrated effect in the bilayer Zr:SiO2-porous SiO2 RRAM devices was also explained and verified by the COMSOL Multiphysics simulation model.
