  • Publication number: 20140198593
    Abstract: A redundancy circuit includes a redundancy decoder, a fuse array, and a decoder. The redundancy decoder decodes a redundancy enable signal generated when an address of a defective cell matches an input address. The decoded redundancy enable signal is used to activate a spare column select line connected with a redundancy block to be substituted for the defective cell designated by the defective cell address. The fuse array includes fuse elements to designate segments in the redundancy block based on availability of the segments. The decoder decodes coding signals from the fuse array to connect at least one of the fuse elements with the spare column select line.
