Patent ID: 7978493

Claim:
A method of reducing sense current in an array of fuses by encoding a bit stream representing a state for each of the fuses in the array of fuses, comprising: counting a number of fuses to be blown in the array of fuses through a first counter receiving the bit stream; contemporaneously counting a number of fuses to remain unblown in the array of fuses through a second counter receiving the bit stream, each counting operation performed according to a common clock cycle; comparing the number of fuses to be blown and the number of fuses to remain unblown in the array of fuses through a comparator receiving output from both the first and the second comparators; inverting each bit of the bit stream based on a result of the comparing; and storing a bit value for use as a selection logic signal for all logic decoding circuits that decode the bit stream, each of the logic decoding circuits coupled to a corresponding fuse storing a bit of the bit stream.
