Abstract
A resistive switching device includes a first material layer between a first electrode and a second electrode. The first material layer has a first region and a second region parallel to the first region. The first region corresponds to a conducting path formed in the first material layer, and is configured to switch from a low-resistance state to a high-resistance state in response to an applied voltage that is greater than or equal to a first voltage. The second region is configured to switch to a first resistance value that is less than a resistance value of the first region in the high-resistance state when the applied voltage is greater than or equal to a second voltage. The first region remains constant or substantially constant when the second region has the first resistance value.
