  • Method of erasing information and device for performing same
    Patent number: 9633739
    Abstract: Methods and devices for erasing information stored on an electronic semiconductor component in a plurality of non-volatile memory elements are described. Irradiating the semiconductor component with erasing radiation until a target dose has been absorbed by the semiconductor component, the erasing radiation penetrating the semiconductor component, results in an ionization effect which influences the concentration of the charge carriers stored on the memory elements such that a statistical distribution of the threshold voltages of the memory elements forms a contiguous region.
    Type: Grant
    Filed: January 19, 2016
    Date of Patent: April 25, 2017
    Assignee: Fraunhofer-Gesellschaft zur Foerderung der angewandten Forschung e.V.
    Inventors: Stefan Hoeffgen, Michael Joester, Jochen Kuhnhenn, Tobias Kuendgen, Stefan Metzger
