abstract = {Memristors are playing an increasingly important role in developing in-memory computing. Versatile memristors which offer both volatile and non-volatile performances can be employed as both memories and selectors, displaying unique advantages for developing novel electronic circuits. Herein, the remarkable multifunctional memristor with switchable operating modes between volatile and non-volatile by regulating compliance currents is implemented in Ag/CIPS/Au (CIPS: CuInP2S6) device. Diode-like volatile memristor performances with the rectification ratio of 103 and an endurance of 500 switching cycles were obtained. Meanwhile, significant non-volatile memory performances with on/off ratio of 103 and retention up to 104 s were also developed, which enables it to be utilized as selectors and memories simultaneously. Moreover, such versatile memristor can emulate the short-term plasticity (STP) and long-term plasticity (LTP) of artificial synapse, demonstrating its advantages in neuromorphic computing applications.}
