  • Voltage regulator for memory
    Patent number: 8004924
    Abstract: A circuit includes a first negative feed back loop coupled to a virtual Vvdd power rail and a true Vdd power rail. A second negative feed back loop is coupled to the virtual Vvss power rail and a true Vss power rail. The virtual rail to virtual rail voltage difference is regulated at the highest threshold voltage between pull-up and pull-down transistors of a memory cell.
    Type: Grant
    Filed: February 18, 2009
    Date of Patent: August 23, 2011
    Assignee: Atmel Corporation
    Inventors: Sylvain Leomant, Jimmy Fort, Arnaud Turier, Laurent Vachez, Lotfi B. Ammar
