摘要:
An integrated circuit and method of testing and repairing the integrated circuit. The integrated circuit includes: a multiplicity of macro-circuits having the same function; a fuse bank, the state of the fuses storing test data indicating at least which macro-circuits failed a test; and means for preventing utilization of failing macro-circuits during operation of the integrated circuit and a method generating a partial good integrated circuit, the method including: providing an integrated circuit have a multiplicity of macro-circuits arranged in one or more groups, each macro-circuit having the same function and a fuse bank containing fuses; testing each macro-circuit prior to a fuse programming operation; programming the fuses in the fuse bank in order to store data indicating at least which macro-circuits failed the testing step; and preventing utilization of each failing macro-circuit during operation of the integrated based on the data stored in the fuse bank.
