US Patent 7274208 - Nanoscale crossbars for programmable logic arrays

There is some interest in using nanoscale crossbars as elements in programmable logic devices. This patent from CalTech research Andre DeHon claims several configurations for nanoscale crossbars used in PLA designs. Claim 1 reads:

1. A programmable logic array (PLA) comprising: a first plurality of nanoscale wires forming PLA inputs; and a restoring inverting arrangement connected with the PLA inputs, comprising a second plurality of nanoscale wires, the restoring inverting arrangement restoring signals on the PLA inputs and inverting the signals on the PLA inputs.
