Abstract:
1. A non-volatile memory device; comprising: a substrate having a surface region; a first dielectric material overlying the surface region of the substrate; a first wordline and a second wordline overlying the first dielectric material, the first wordline being associated with a first resistive switching device and the second wordline being associated with a second resistive switching device; a second dielectric material overlying the first wordline and the second wordline; a third wordline and a fourth wordline overlying the second dielectric material, the third wordline being associated with a third resistive switching device and the fourth wordline being associated with a fourth resistive switching device; a resistive switching material conformably configured within a via structure, the via structure being configured to extend at least in the second dielectric material overlying the first dielectric material between the first wordline and the second wordline and abutting the first wordline and the second wordline, and between the third wordline and the fourth wordline and abutting the third wordline and the fourth wordline; a metal material disposed in the via structure overlying the resistive switching material, a single bitline connecting to the metal material in the via structure and being configured to electrically connect the first resistive switching device, the second resistive switching device, the third resistive switching device, and the fourth resistive switching device to a control circuit on the substrate.
