Bradley Craig White 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).

  • Dual threshold gate array or standard cell power saving library circuits
    Patent number: 6668358
    Abstract: A method is disclosed wherein a subset of logic blocks on an ASIC simiconductor logic chip is examined for replacement by functionally equivalent logic blocks in the ASIC library. The functionally equivalent logic block replacements are designed to exhibit, on average, significantly less subthreshold leakage currents. The replacement blocks are slower performing blocks, and therefore, checks are made to ensure that timing requirements are not violated.
    Type: Grant
    Filed: October 1, 2001
    Date of Patent: December 23, 2003
    Assignee: International Business Machines Corporation
    Inventors: David Michael Friend, Nghia Van Phan, Byron D. Scott, Daniel Lawrence Stasiak, Bradley Craig White
