  • Reprogrammable integrated circuit (IC) with overwritable nonvolatile storage
    Patent number: 7123517
    Abstract: A reprogrammable integrated circuit (IC) including overwritable nonvolatile storage cells. Cell contents are compared in a differential sense amplifier against a variable reference signal that has a number of selectable reference levels corresponding to reprogrammed cell threshold voltages. With each write cycle the nonvolatile storage cells are overwritten and then, compared against a different, e.g., higher, selectable reference level.
    Type: Grant
    Filed: October 7, 2004
    Date of Patent: October 17, 2006
    Assignee: International Business Machines Corporation
    Inventors: Matthew Breitwisch, Chung H. Lam, Steven Mittl, Jian W. Zhu
