    摘要： A high-order mode surface acoustic wave device includes a piezoelectric substrate (11) formed from a LiTaO3 or LiNbO3 crystal and an interdigital transducer electrode (12) embedded in a surface of the piezoelectric substrate (11) to use a surface acoustic wave in a high-order mode. Further, the high-order mode surface acoustic wave device may include a film (13) or substrate stacked on the piezoelectric substrate (11), and may include a support substrate (11) and/or a multi-layer film (15) provided in contact with a surface opposite to the surface of the piezoelectric substrate (11) on which the interdigital transducer electrode (12) is provided. The high-order mode surface acoustic wave device may achieve good characteristics and maintain a sufficient mechanical strength even in a high frequency band of 3.8 GHz or greater.

    摘要： There is provided a neural network circuit device including a plurality of synapse circuits storing a synaptic coupling weight and a neuron circuit connected to the plurality of synapse circuits. The plurality of synapse circuits store the synaptic coupling weight in a non-volatile manner and output a voltage signal having a magnitude based on the stored synaptic coupling weight in response to an input signal. The neuron circuit includes a neuron MOS transistor having a floating gate and a plurality of control gates which are capacitively coupled to the floating gate and to which the voltage signals from the plurality of synapse circuits are input respectively, and a pulse generator outputting a pulse signal by turning on or off the neuron MOS transistor.

    摘要： The present invention provides a device with low power and high performance, which can be applied to sensor nodes, a sensor node using the same, an access controller, a data transfer method, and execute a processing method in a microcontroller. The device has: an MRAM; a non-volatile CPU configured to include a nonvolatile memory; a non-volatile FPGA-ACC configured to include a nonvolatile memory and execute a part of operations on the nonvolatile CPU; and a power-gating control unit that controls power supply to each memory cell in the MRAM, the non-volatile CPU, and the non-volatile FPGA-ACC. The device is further provided with an access controller that controls accesses to the MRAM by reading data in advance and backing up the data when data is to be read from the MRAM.

    摘要： A display device includes a substrate including a first surface, and a second surface positioned at a side opposite to the first surface; a first light-emitting element located at a lateral side of the substrate; a plurality of light-receiving elements located at a second surface side of the substrate; a plurality of second light-emitting elements located on the first surface of the substrate; and a first drive element controlling driving of the second light-emitting elements based on output of the light-receiving elements. A light-emitting surface of the first light-emitting element is oriented in a first direction. The first direction is parallel to a direction from the first surface toward the second surface. Light-emitting surfaces of the second light-emitting elements are oriented in a second direction. The second direction is from the second surface toward the first surface.
