Patent ID: 7782649

Claim:
An apparatus, comprising: a ferroelectric film comprising one or more domains, the ferroelectric film comprising a first surface and a second surface, the first surface being opposite the second surface; an electrode coupled with the first surface; an electrically conductive thin film coupled with the second surface, the electrically conductive thin film being sufficiently conductive that a controlled bias field applied between the electrically conductive thin film and the electrode is sufficient to grow, shrink, or actively maintain a size of the one or more domains disposed between the electrically conductive thin film and the electrode; and one or more electrically conductive mesh structures coupled to the electrically conductive thin film to supply bias voltage to grow, shrink, or actively maintain the one or more domains to a desired size, the electrically conductive mesh structures comprising openings in the mesh structures to allow a seek-and-scan probe to perform read or write operations on the one or more domains.
