A polymer‐memory device based on a copolymer containing carbazole (donor) and Eu‐complex (acceptor) groups in a metal/insulator/metal architecture is described. The nonvolatile device has two distinctive bistable conductivity states, and exhibits a high ON/OFF current ratio, a fast response time, and acceptable retention under ambient conditions. Application of a potential sets the device to the high‐conductivity ON state by generating holes (see Figure).
