Integrated circuit redundancy and method for achieving high-yield production

An electronic circuit forming a digital system constructed in integrated circuit form on a single semiconductor die, comprising:

• plural configurations of the electronic circuit formed on the die, each configuration including a multiplicity of interconnected circuit elements;
• and
• each configuration including a number of voter means intercoupling corresponding and predetermined first and second ones of the circuit elements, the voter means of each configuration being connected to receive output signals from the corresponding first ones of the circuit elements of the configurations to produce therefrom a voted output signal that is indicative of a majority of the received output signals, each of the voter means including latch means for temporarily holding the voted output signal.

The integrated circuit of claim 18, wherein each circuit element of each configuration is a member of at least one of the circuit element groups of that configuration.

A large-scale integration of an electronic circuit comprising:

• a substrate;
• a plurality of substantially identical replications of the electronic circuit formed on the substrate, each replication including a multiplicity of circuit element groups each comprising a number of circuit elements, each circuit element group having a corresponding circuit element group of substantially identical configuration forming a part of each of the other replications;
• voter means for each of the circuit element group of each replication for receiving output signals provided by the circuit element group and the corresponding ones of the circuit element group to produce therefrom a voted signal that is indicative of the majority of said received output signals.

An electronic circuit constructed in integrated circuit form on a single semiconductor die, comprising:

• plural configurations of the electronic circuit formed on the die, each configuration including a multiplicity of interconnected circuit elements forming predetermined circuit element groups, each circuit element group being configured to produce a group output signal, each circuit element group of each configuration having a corresponding, substantially identically configured circuit element group in each of the other configurations;
• and
• each circuit element group including voter means connected to receive the group output signal produced by the circuit element group, and the group output signal produced by the corresponding circuit element groups, for producing a voted output signal that is indicative of a majority of the received group output signals.
