Abstract:
1. A non-volatile field programmable gate array, comprising: a reconfigurable logic component; a transistor device coupled to the reconfigurable logic component, comprising a gate structure, a first impurity region, and a second impurity region, the first impurity region being operably coupled to the reconfigurable logic component; and a resistive switching device coupled to the transistor device and to the reconfigurable logic component, the resistive switching device comprising a bottom electrode coupled to the first impurity region, a top electrode including at least a portion comprising an active metal material spatially extending in a first direction, and a resistive switching element in physical and electrical contact with the active metal material of the top electrode and to the bottom electrode at an intersecting region between the bottom electrode and the top electrode, wherein the resistive switching device stores a resistance state from a plurality of resistance states that indicates a configuration code for the reconfigurable logic component; wherein the resistive switching element comprises an amorphous silicon material configured to allow formation of a filament structure therein, wherein the filament structure comprises a metal region comprising metal particles from the active metal material.
