  • Patent number: 12260909
    Abstract: Operating a selector device that controls access of a signal to a memory element may comprise applying a main operating voltage pulse and a refresh voltage pulse to the selector device. The refresh voltage pulse and main operating voltage pulse have opposite polarities. A magnitude of the main operating voltage pulse is greater than or equal to a threshold voltage for turning on the selector device, and a maximum magnitude of the refresh voltage pulse is less than the threshold voltage. The refresh voltage pulse reduces a difference between the threshold voltage and a turn-off voltage of the selector device, and may be applied immediately before or immediately after the main operating voltage pulse. An electronic circuit may include the selector device and a driving circuit for apply the pulses. A nonvolatile memory may include the driving circuit and a plurality of nonvolatile memory elements each including a selector device.
