A memristor is a two‐terminal electronic device whose observed conductance is dependent on the history of the voltage that has been applied across the device. In this effort, poly(11‐(9H‐carbazol‐9‐yl)undecyl methacrylate) (PUMA) is fabricated into a two‐terminal device with Al and ITO electrodes and exhibits a number of signature memristor characteristics such as an irreversible transition from an insulator to a conductor at a specific DC voltage and hysteresis in the AC response. A PUMA‐based device could transition through a multitude of conductance states with varying voltage, allowing the device to exhibit spike‐timing‐dependent‐plasticity, an essential feature in replicating the behavior of biological synapses.
