Method and an apparatus for a hard-coded bit value changeable in any layer of metal |
摘要 |
A method is disclosed to make a hard-coded bit in an integrated circuit on a semiconductor chip changeable in any one and only one metal layer of the semiconductor chip. In one embodiment, the method further comprising fabricating a cell on each metal layer of the semiconductor chip and a logic circuitry on the semiconductor chip. The cells are coupled to the inputs of the logic circuitry. The output of the logic circuitry changes in response to a change in any single cell to cause the hard-coded bit to change.
