Abstract:
1. A non-volatile storage apparatus, comprising: a monolithic three dimensional array of non-volatile storage elements arranged in blocks, wherein each non-volatile storage element of the array of non-volatile storage elements comprises a first electrode, a second electrode, and a carbon-based reversible resistivity switching material and a metal oxide reversible resistivity switching material between the first electrode and the second electrode; and control circuitry in communication with the non-volatile storage elements, the control circuitry is configured to set the non-volatile storage elements to a low resistance state with a first polarity signal and reset the non-volatile storage elements to a higher resistance state with a second polarity signal, a polarity of the first polarity signal is opposite to a polarity of the second polarity signal.
