    Abstract: A semiconductor device in which a memory region at each level of a memory device can be changed is provided. The semiconductor device includes a memory device including a first and a second memory circuit and a control circuit. The first memory circuit includes a first capacitor and a first transistor which has a function of holding charges held in the first capacitor. The second memory circuit includes a second transistor, a second capacitor which is electrically connected to a gate of the second transistor, and a third transistor which has a function of holding charges held in the second capacitor. The first and the third transistors each have a semiconductor layer including an oxide semiconductor, a gate, and a back gate. The voltage applied to the back gate of the first or the third transistor is adjusted, whereby the memory region of each of the first and the second memory circuit is changed.

    Abstract: Provided is a semiconductor device with a novel structure in which the power consumption can be reduced. The semiconductor device includes a sensor, a sample-and-hold circuit to which a sensor signal of the sensor is input, an analog-digital converter circuit to which an output signal of the sample-and-hold circuit is input, a control circuit, a battery, and an antenna. The sample-and-hold circuit includes a first selection circuit, a plurality of signal retention circuits, and a second selection circuit, and the control circuit performs a control so that a potential corresponding to the sensor signal is retained in the plurality of signal retention circuits successively by the first selection circuit in a first period during which power is supplied from the battery, and performs a control so that the output signal based on the potential retained in the plurality of signal retention circuits is output by the second selection circuit in a second period during which power is supplied from outside through the antenna.

    Abstract: To improve color reproduction areas in a display device having light-emitting elements. A display region has a plurality of picture elements. Each picture element includes: first and second pixels each including a light-emitting element which has a chromaticity whose x-coordinate in a CIE-XY chromaticity diagram is 0.50 or more; third and fourth pixels each including a light-emitting element which has a chromaticity whose y-coordinate in the diagram is 0.55 or more; and fifth and sixth pixels each including a light-emitting element which has a chromaticity whose x-coordinate and y-coordinate in the diagram are 0.20 or less and 0.25 or less, respectively. The light-emitting elements in the first and second pixels have different emission spectrums from each other; the light-emitting elements in the third and fourth pixels have different emission spectrums from each other; and the light-emitting elements in the fifth and sixth pixels have different emission spectrums from each other.
