Configurable crossbars are the easiest computational structures to fabricate at the nanoscale. By creating multiple types of crossbars and assembling them into larger structures, we may implement general computation. Architectures for diode-based and transistor-based logic are presented, along with latching mechanisms. We present simulation results from defect-tolerance studies on two applications (a 3-bit adder and a 4-bit microprocessor) mapped onto defective, nanoelectronic fabrics, and outline strategies for fault tolerance.
