Defect-Tolerant Computing Circuits.As feature sizes shrink in integrated circuits, it becomes increasingly more expensive to avoid mistakes in manufacturing. At some stage, only circuits designed to tolerate manufacturing defects will be practical to build. The designs below for internally-redundant demultiplexer circuits show how a standard digital building block (a demultiplexer circuit) can be re-engineered to tolerate manufacturing defects.Defect-tolerant demultiplexers for nano-electronics constructed from error-correcting codes P.J.
