Gene Vance has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Fuse trimming in plastic package devices
    Patent number: 5412594
    Abstract: A method and apparatus provide fuse trimming or analog integrated circuit parameters in plastic packages. The apparatus includes an electrically interruptible circuit element, such as a fuse; a level reading unit which reads the state of the electrically interruptible circuit element and generates a code in response to the state; a state altering unit, such as a current source for providing a blow current; and a control circuit. A test level reading device allows screening for marginally-blown fuses. A switchable element removes applied voltage from fuses when the fuse is not being blown or read to prevent fuse regrowth.
    Type: Grant
    Filed: August 8, 1994
    Date of Patent: May 2, 1995
    Assignee: Advanced Micro Devices, Inc.
    Inventors: Miki Moyal, Thomas Brennan, Gene Vance
