    摘要: Memory devices and methods for operating such devices are described herein. A method as described herein for operating a memory device includes applying a sequence of bias arrangements across a selected metal-oxide memory element to change the resistance state from a first resistance state in a plurality of resistance states to a second resistance state in the plurality of resistance states. The sequence of bias arrangements comprise a first set of one or more pulses to change the resistance state of the selected metal-oxide memory element from the first resistance state to a third resistance state, and a second set of one or more pulses to change the resistance state of the selected metal-oxide memory element from the third resistance state to the second resistance state.
