A Multilevel Memory Based on Proton-Doped Polyazomethine with an Excellent Uniformity in Resistive Switching

The uniformity of operating parameters in organic nonvolatile memory devices is very important to avoid false programming and error readout problems. In the present work, we fabricated an organic resistive-switching memory based on protonic-acid-doped polyazomethine (PA-TsOH), which demonstrates an excellent operative uniformity and multilevel storage capability. The deliberate tuning of the resistance states can be attributed to the electric-field-controlled molecular doping of the imine-containing polymers.
