Abstract
A redundancy programming circuit employing a two EPROM cell CAM for storing programmed states of redundant elements. The CAMs are disposed aside a memory array and word lines of the array are extended to the CAMs for programming the CAMs. Two word lines are coupled to each EPROM cell so that programming can still be achieved in the event one of the lines is defective.
