ABSTRACT:
A semiconductor memory device provides redundancy using a decoder which examines a memory address and outputs the contents of memory at that address if the decoder determines that the address signal is selecting a correct bit cell in the memory, or clamps the output at a predetermined level if the decoder determines that the address signal is selecting an error bit cell in the memory.
