    • A nonvolatile optical memory element in which a ferromagnetic body is provided on a semiconductor causes such a problem that in a case where magnetization of the ferromagnetic body is read by light, magneto-optical response becomes very small when the ferromagnetic body is small in volume. The present invention provides a memory element, a memory device, and a data reading method, each of which is applicable to data reading from a nonvolatile optical memory element. In a nonvolatile optical memory element having a structure in which a ferromagnetic body is provided on a semiconductor that is connected to an optical waveguide, electrons are injected into the semiconductor via the ferromagnetic body so that the electrons that are spin-polarized according to a magnetization direction of the ferromagnetic body are injected into the semiconductor, thereby enlarging a region in which a photomagnetic effect occurs effectively. By applying an electric pulse and an optical pulse to the nonvolatile optical memory element, it is possible to effectively read recorded data according to a magnetization direction of the ferromagnetic body.

    • An antenna array part constituting a communication antenna is composed of a plurality of antenna elements. The antenna elements are arranged on an arc. This allows radio waves to be irradiated also in the exact transverse direction of the antenna array part, thereby making available the communications with an RFID tag positioned in the exact transverse direction. By shifting the phase of a radio frequency signal supplied to each antenna element or adjusting the amplitude of the radio frequency signal, it is possible to change the direction of radio beams irradiated from the antenna array part or expand the width of the radio beams thus making available with RFID tags present in a wider area.
