Memristors with enormous storage capacity and superior processing efficiency are of critical importance to overcome the Moore's Law limitation and von Neumann bottleneck problems in the big data and artificial intelligence era. In particular, the integration of multi-functionalities into a single memristor promises an essential strategy of obtaining a highperformance electronic device that satisfies the nowadays increasing demands of data storage and processing. In this contribution, we report a proof-of-concept polymer memristive processing-memory unit that demonstrates programmable information storage and processing capabilities. By introducing redox active moieties of triphenylamine and ferrocene onto the pendants of fluorene skeletons, the conjugated polymer exhibits triple oxidation behavior and interesting memristive switching characteristics. Associated with the unique electrochemical and electrical behavior, the polymer device is capable of executing multilevel memory, decimal arithmetic operations of addition, subtraction, multiplication and division, as well as simple Boolean logic operations.
