A solution‐processable PFTPA‐convalently grafted reducedgrapheneoxide (RGO‐PFTPA) was synthesized by the 1,3‐dipolar cycloaddition of azomethine ylide. Bistable electrical switching and nonvolatilerewritablememory effects were demonstrated in a sandwich structure of indium tin oxide/RGO‐PFTPA/Al. The switch‐on voltage of the as‐fabricated device was around −1.4 V, and the ON/OFF‐state current ratio
