Publication number: 20240134605Abstract: A semiconductor device with a novel structure is provided. The semiconductor device includes a cell array performing a product-sum operation of a first layer and a product-sum operation of a second layer in an artificial neural network, a first circuit from which first data is input to the cell array, and a second circuit to which second data is output from the cell array. The cell array includes a plurality of cells. The cell array includes a first region and a second region. In a first period, the first region is supplied with the t-th (t is a natural number greater than or equal to 2) first data from the first circuit and outputs the t-th second data according to the product-sum operation of the first layer to the second circuit. In the first period, the second region is supplied with the (t+1)-th first data from the first circuit and outputs the (t+1)-th second data according to the product-sum operation of the second layer to the first circuit.Type: ApplicationFiled: February 24, 2022Publication date: April 25, 2024Inventors: Yoshiyuki KUROKAWA, Hiromichi GODO, Kazuki TSUDA, Satoru OHSHITA, Hidefumi RIKIMARU

Publication number: 20240138167Abstract: An electronic device having an eye tracking function is provided. The electronic device includes a display device and an optical system. The display device includes a first light-emitting element, a second light-emitting element, a sensor portion, and a driver circuit portion. The sensor portion includes a light-receiving element. The first light-emitting element has a function of emitting infrared light or visible light. The second light-emitting element has a function of emitting light of a color different from that of light emitted from the first light-emitting element. When the first light-emitting element emits infrared light, the light-receiving element has a function of detecting the infrared light that is emitted from the first light-emitting element and reflected by an eyeball of a user.Type: ApplicationFiled: February 24, 2022Publication date: April 25, 2024Inventors: Hiromichi GODO, Yoshiyuki KUROKAWA, Kouhei TOYOTAKA, Kazuki TSUDA, Satoru OHSHITA, Hidefumi RIKIMARU

Patent number: 11921919Abstract: To provide a novel electronic device. The electronic device includes a housing and a display device. The display device includes a first layer, a second layer, and a third layer. The first layer, the second layer, and the third layer are provided in different layers. The first layer includes a driver circuit and an arithmetic circuit. The second layer includes pixel circuits and a cell array. The third layer includes light-receiving devices and light-emitting devices. The pixel circuits each have a function of controlling light emission of the light-emitting device. The driver circuit has a function of controlling the pixel circuits. The arithmetic circuit has a function of performing arithmetic processing on the basis of first data corresponding to currents output from the light-receiving devices and second data corresponding to a potential held in the cell array.Type: GrantFiled: February 15, 2022Date of Patent: March 5, 2024Assignee: Semiconductor Energy Laboratory Co., Ltd.Inventors: Yoshiyuki Kurokawa, Hiromichi Godo, Kouhei Toyotaka, Kazuki Tsuda, Satoru Ohshita, Hidefumi Rikimaru
