Abstract: The present disclosure provides mechanisms for reducing and suppressing random telegraph noise (RTN) for a crossbar circuit. A processing device may perform a programming process to program the conductance of a resistive random-access memory (RRAM) device in the crossbar circuit to a target conductance value.

If the RTN value associated with the RRAM device is not within a predetermined range of acceptable RTN values, one or more noise-reduction voltages may be applied to the RRAM device until the RTN value associated with the RRAM device is within the predetermined range of acceptable RTN values.
