  • Programmable impedance device
    Patent number: 6456529
    Abstract: A programmable impedance element (204) is implemented using integrated circuit techniques and devices. An impedance of the programmable impedance element is adjusted by appropriately configuring the element. The programmable impedance element has a range of impedance values, and is configurable to be a value within this range. In an embodiment, the programmable impedance element is implemented using a floating gate device (230), and is nonvolatile.
    Type: Grant
    Filed: September 27, 2001
    Date of Patent: September 24, 2002
    Assignee: SanDisk Corporation
