Reservoir computing (RC) system is based upon the reservoir layer, which non-linearly transforms input signals into high-dimensional states, facilitating simple training in the readout layer. These layers require diffusive and drift memristors, respectively. However, the integration of these increases the structural complexity of RC system. Herein, a reconfigurable resistive switching memory (RSM) implementing both diffusive and drift dynamics is demonstrated. The RSM operates in a volatile threshold switching (TS) mode under a weak electric field and exhibits short-term dynamics that are confirmed to be applicable as reservoir elements in RC systems. Meanwhile, the RSM operates in a non-volatile bipolar switching (BS) mode under a strong electric field, and the conductance modulation metrics forming the basis of synaptic weight update in readout layer are validated. Finally, an RC system is designed for the application of reconfigurable RSM and performs real-time recognition on Morse code.
