Patents by Inventor Ma Fan Yung

Ma Fan Yung 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).

  • Zero static power fuse cell for integrated circuits
    Patent number: 6839298
    Abstract: A fuse cell with reduced or no static power dissipation is disclosed. The fuse cell utilizes a latch to store the state of the fuse. The use of the latch avoids having a pull-up power source being coupled to ground when the fuse is uncut as with conventional fuse cells.
    Type: Grant
    Filed: July 11, 2001
    Date of Patent: January 4, 2005
    Assignee: Infineon Technologies Aktiengesellschaft
    Inventor: Ma Fan Yung
  • Zero static power programmable fuse cell for integrated circuits
    Patent number: 6603344
    Abstract: A software programmable fuse cell which reduces or eliminates static power consumption is disclosed. The programmable fuse cell includes programmable and non-programmable operating modes. Depending on the operating mode, the fuse cell output is determined by the actual state of the fuse or which fuse state the fuse cell is simulating. To reduce static power consumption, a latch is used to store the actual or simulated fuse state.
