Abstract:
1. A non-volatile memory device structure comprising: a substrate having a surface region; a first dielectric material overlying the surface region of the substrate; a state change device overlying the first dielectric material, the state change device comprising a first wiring structure configured to spatially extend in a first direction, a switching element comprising at least a first undoped amorphous silicon material overlying the first wiring structure, and a second wiring structure configured to spatially extend in a second direction perpendicular to the first direction, the second wiring structure having a first portion and a second portion, the first portion comprising a first metal material overlying with the switching element; and a first thin film transistor device operably connected with and at least in part overlying the state change device and comprising a first active region, a second active region, a gate structure overlying a gate dielectric layer, and a channel region, the first active region being configured to be in electrical contact with the first portion of the second wiring structure.
