Abstract
A method includes applying a voltage bump across a combined memory device comprising a volatile selector switch and a nonvolatile switch, in which the voltage bump changes a state of the volatile selector switch from a high resistance to a low resistance but does not change a state of the nonvolatile switch. A read voltage that is lower than the voltage bump across the combined memory device to read a state of the nonvolatile switch.
