Steve Gualandri 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: 7355894
    Abstract: A flash memory device has an array of flash memory cells, a detector for detecting an external voltage applied to the flash memory device, and a command control circuit for controlling access to the array of flash memory cells. The command control circuit is adapted to perform a method of programming one or more of the flash memory cells when the external voltage exceeds a predetermined value and when the command control circuit receives a program command. The method includes, in response to the program command and the detected external voltage, applying an internally-generated programming voltage to a control gate of the one or more flash memory cells and applying a voltage pulse to a drain of the one or more flash memory cells while the control gate is at the internally-generated programming voltage.
