Redundancy CAM using word line from memory

A redundancy programming circuit 31 employs a two EPROM cell CAM for storing programmed states of redundant memory elements. The CAMs are disposed aside a memory array 17a 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...

Summary:A redundancy programming circuit 31 employs a two EPROM cell CAM for storing programmed states of redundant memory elements. The CAMs are disposed aside a memory array 17a 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.
