abstract = {In this letter, bipolar resistive switching in TiO2-based
memory elements deposited on CMOS-compatible W-plugs is
examined. By comparison with a Pt/TiO2/W resistive switch,
it is demonstrated that the use of a 5-nm-thin Ti or W
interlayer between the Pt top electrode and the 25-nm TiO2
film is the key step for the release from the necessity of
electroforming, which is usually required in redox-based
resistive switching elements. This is explained by an
intentional barrier lowering between the oxide and the
electrode materials. The forming-free characteristics on
W-plugs make the devices very attractive for future
nonvolatile memory applications.},
