Associative interconnection circuit

摘要: The disclosed apparatus uses an associative memory technique for the selective coupling of circuit elements to a data bus wherein each element is assigned address and coupled when it receives said on its lines. further comprises reconfiguration control unit assigning addresses all elements, allowing be addressed at random. When one function substituted another, assigns replaced replacing element. In this way, user continues use same address, making replacement transparent user, thereby avoiding reprogramming by user. preferred embodiment stored in nonvolatile so that will not lost power turned off, but electrically reprogrammable if necessary or desired. Power may also supplied through line uncoupled, disconnected, reducing drive current required operate array elements. This especially useful wafer scale integration where plurality functional are contained wafer. can test designate some operable remaining as spares. Upon failure which being used, assign unused original Thus, capability random sparing accomplished single way
