Abstract
The present invention concerns a method and apparatus for disabling columns using a local fuse decoding system. The present invention uses local decoding in order to use a number of fuses that is less than the number of columns in order to disable column failures. This is particularly useful when the fuse pitch is greater than the column pitch which does not allow for a fuse to be implemented in each column.
