AFM image of 17 nanodevices with a zoom‐in cartoon schematically shows an individual crosspoint device consisting of two Pt metal electrodes separated by a TiO 2 bi‐layer memristive material. By applying an electric field across the memristive material, oxygen vacancies can drift up and down, leading to four current‐transport end‐states. The switching between these end‐states results in a family of nanodevices.
