摘要
A spare logic circuit for implementing any one of a plurality of logic gates includes a multiplexer circuit whose select inputs are utilized as logic gate inputs, and whose output is utilized as a logic gate output. Each of a plurality of data inputs of the multiplexer circuit is configured to receive one of first and second logic voltage levels which define the desired logic function. By modifying a single photolithographic mask, the spare logic gate can be: configured to perform the desired logic function; connected into a target logic circuit; or both configured and connected into a target logic circuit.
