Abstract:
A non-volatile resistive switching memory device. The device includes a first electrode, a second electrode, a switching material in direct contact with a metal region of the second electrode, and a resistive material disposed between the second electrode and the switching material. The resistive material has an ohmic characteristic and a resistance substantially the same as an on state resistance of the switching device. The resistive material allows for a change in a resistance of the switching material upon application of voltage pulse without time delay and free of a reverse bias after the voltage pulse. The first voltage pulse causes a programming current to flow from the second electrode to the first electrode. The resistive material further causes the programming current to be no greater than a predetermined value.
