US Patent 7605408 - Electron wave reconfigurable circuitry

As Moore's Law becomes more difficult to fulfill there is some growing interest in reconfigurable computing and dynamic circuit elements such as the memristor which provides memory dependent effects in nanoelectronic devices. This patent from Nokia teaches using a graphene material layer to achieve another variation of reconfigurable electronics in which the graphene also produces a memory effect used to control electron wave transmission probability. Claim 1 reads:

1. An apparatus, comprising:

a nanoscale material layer; and

a programmable element in close proximity to at least a first section of the nanoscale material layer;

wherein the programmable element is programmable to a first state to interfere with an electron wave in at least the first section of the nanoscale material layer in a first manner, and

programmable to a second state to interfere with the electron wave in a second manner.
