Patents by Inventor Matthew M. Ma

Matthew M. Ma 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).

  • Patent number: 8719600
    Abstract: The operating voltage of an integrated circuit (e.g., a processor) is changed in response to one or more conditions (e.g., a laptop computer is connected to an AC power source). Both the operating frequency and the operating voltage of the integrated circuit are changed. The voltage regulator providing the operating voltage to the integrated circuit is caused to transition between voltage levels using one or more intermediate steps. The integrated circuit continues to operate in the normal manner both at the new voltage and throughout the voltage transition.
    Type: Grant
    Filed: August 30, 2012
    Date of Patent: May 6, 2014
    Assignee: Intel Corporation
    Inventors: Stephen H. Gunther, Robert Greiner, Matthew M. Ma, Kevin Dai
