  • Method and system for device reconfiguration for defect amelioration
    Patent number: 8121807
    Abstract: Embodiments of the present invention are directed to cost-effective defect amelioration in manufactured electronic devices that include nanoscale components. Certain embodiments of the present invention are directed to amelioration of defects in electronic devices that contain nanoscale demultiplexers. In certain embodiments of the present invention, the nanoscale-demultiplexer-containing devices include reconfigurable encoders. In one embodiment of the present invention, the table of codes within a reconfigurable encoder is permuted, and a device is configured in accordance with the permuted codes, in order to produce a permuted table of codes that, when input to an appropriately configured nanoscale demultiplexer, produces correct outputs despite defects in the nanoscale demultiplexer.

  • Defect-tolerant demultiplexers based on threshold logic
    Patent number: 7899091
    Abstract: Embodiments of the present invention include defect-tolerant demultiplexer crossbars that employ, or that can be modeled by demultiplexer crossbars that employ, threshold logic “TL” elements. The threshold-logic elements provide for tolerance for signal variation on internal signals lines of a defect-tolerant demultiplexer crossbar, and thus tolerance for defects which produce internal signal variation.
