Methods and Apparatus for Resistive Random Access Memory (RRAM)

摘要

Methods and apparatuses for a resistive random access memory (RRAM) device are disclosed. The RRAM device comprises a bottom electrode, a resistive switching layer disposed on the bottom electrode, and a top electrode disposed on the resistive switching layer. The resistive switching layer is made of a composite of a metal, Si, and O. There may be an additional tunnel barrier layer between the top electrode and the bottom electrode. The top electrode and the bottom electrode may comprise multiple sub-layers.
