We report an organic, nonvolatile memory based on dopant concentration-induced conductance changes in a conjugated polymer. Consisting of a polymer poly [2-methoxy-5-(2′-ethylhexyloxy)-p-phenylene vinylene] (MEH-PPV)/ionic conductor (RbAg4I5) bilayer sandwiched between two metal electrodes, the device is electrically switched between its low-conductance “off” state and high-conductance “on” state reversibly and repeatedly with on/off ratios above two orders of magnitude and pulse durations as short as 1 μs when a voltage exceeding its threshold values (>+3.5 V or <−3.8 V) is applied. The conductance change is attributed to the injection/depletion of iodide dopant ions in the MEH-PPV layer by the applied electric field.
