Various embodiments of the present invention are directed to crossbar
array designs that interfaces wires to address wires, despite
misalignments between electrical components and wires. In one embodiment,
a nanoscale device may be composed of a first layer of two or more wires
and a second layer of two or more address wires that overlays the first
layer. The nanoscale device may also include an intermediate layer
positioned between the first layer and the second layer. Two or more
redundant electrical component patterns may be fabricated within the
intermediate layer so that one or more of the electrical component
patterns is aligned with the first and second layers.
