Patent ID: 7405462

Claim:
A reconfigurable logic device, comprising: a look-up table (LUT), comprising; a plurality of LUT input signals; an array of programmable impedance devices operably coupled to the plurality of LUT input signals, each programmable impedance device comprising: a first electrode operably coupled to one of the plurality of LUT input signal; a second electrode disposed to form a junction wherein the second electrode at least partially overlaps the first electrode; and a programmable material disposed between the first electrode and the second electrode at least at the junction, the programmable material operably coupling the first electrode and the second electrode such that each programmable impedance device exhibits a non-volatile programmable impedance; at least one LUT output signal operably coupled to at least one of the array of programmable impedance devices; and at least one storage element configured for sampling the at least one LUT output signal.
