  • Method and apparatus for initializing an integrated circuit using compressed data from a remote fusebox
    Patent number: 6577156
    Abstract: A method and apparatus for initializing an integrated circuit using compressed data from a remote fusebox allows a reduction in the number of fuses required to repair or customize an integrated circuit and allows fuses to be grouped outside of the macros repaired by the fuses. The remote location of fuses allows flexibility in the placement of macros having redundant repair capability, as well as a preferable grouping of fuses for both programming convenience and circuit layout facilitation. The fuses are arranged in rows and columns and represent control words and run-length compressed data to provide a greater quantity of repair points per fuse. The data can be loaded serially into shift registers and shifted to the macro locations to control the selection of redundant circuits to repair integrated circuits having defects or to customize logic.

  • Semiconductor wiring technique for reducing electromigration
    Patent number: 6308302
    Abstract: An integrated circuit chip having at least one source pin and a plurality of sink pins. A wire segment connects the source pin to at least one of the sink pins and includes at least two segments where one of the segments is larger than the other where electromigration is likely to occur.

  • Wiring design tool improvement for avoiding electromigration by determining optimal wire widths
    Patent number: 5737580
    Abstract: A method for wiring IC chips such that electromigration criteria are met while minimizing the effect on overall chip wireability. A technique to optimize the width of automatically routed wire segments so that these widths are adequate to support the electromigration current on that net as a function of the capacitive loading of the net itself.
