  • Imbalanced sense amplifier fuse detection circuit
    Patent number: 6426668
    Abstract: A method and structure to provide a circuit adapted to sense the status of a fuse includes an imbalanced sense amplifier latch which includes first and second nodes connected to the fuse. The first node is connected to a fuse and is weaker than the second node, allowing the first node to sense a different voltage level. The voltage difference between the nodes indicates the conductive status of the fuse.
