Abstract
A plurality of fuses are arranged in pairs and configured such that each pair of fuses represents a data bit when one fuse of the pair is blown; represents an un-programmed bit when no fuse of the pair is blown; and represents a zero-ized bit when both fuses of the pair are blown. A fuse programming system programs the fuses of the pairs such that each pair represents a bit, comprising blowing a first fuse of a pair to represent a '1' bit, blowing a second fuse of a pair to represent a '0' bit, and blowing both fuses of a pair to represent a zero-ized pair, whereby if neither fuse of a pair is blown represents a null, un-programmed bit.
