    Abstract: An object is to provide a semiconductor device that automatically adjusts the luminance of a display device. The semiconductor device includes an illuminometer, a threshold detector, a timing controller, a digital-to-analog converter circuit, a first display panel, and a second display panel. The illuminance of external light is measured with the illuminometer, and the threshold value of digital video data is determined by the threshold detector in accordance with the illuminance. The timing controller generates a signal for the first display panel or a signal for the second display panel on the basis of the threshold value and video data transmitted from the outside. The signal for the first display panel and the signal for the second display panel are input to one digital-to-analog converter circuit and converted into digital signals, and the obtained digital signals are input to a corresponding one of the first display panel and the second display panel.

    Abstract: A nonvolatile semiconductor device which can be driven at low voltage is provided. A nonvolatile semiconductor device with low power consumption is provided. A Schmitt trigger NAND circuit and a Schmitt trigger inverter are included. Data is held in a period when the supply of power supply voltage is continued, and a potential corresponding to the data is stored at a node electrically connected to a capacitor before a period when the supply of power supply voltage is stopped. By utilizing a change in channel resistance of a transistor whose gate is connected to the node, the data is restored in response to the restart of the supply of power supply voltage.

    Abstract: Data of a register in a programmable logic element is retained. A volatile storage circuit and a nonvolatile storage circuit are provided in a register of a programmable logic element whose function can be changed in response to a plurality of context signals. The nonvolatile storage circuit includes nonvolatile storage portions for storing data in the register. The number of nonvolatile storage portions corresponds to the number of context signals. With such a structure, the function can be changed each time context signals are switched and data in the register that is changed when the function is changed can be backed up to the nonvolatile storage portion in each function. In addition, the function can be changed each time context signals are switched and the data in the register that is backed up when the function is changed can be recovered to the volatile storage circuit.

    Abstract: To provide a semiconductor device in which power consumption can be reduced and operation delay due to a stop and a restart of supply of power supply voltage can be suppressed and a driving method thereof. A potential corresponding to data held in a period during which power supply voltage is continuously supplied is saved to a node connected to a capacitor before the supply of power supply voltage is stopped. By utilizing change of channel resistance of a transistor whose gate is the node, data is loaded when the supply of power supply voltage is restarted.

    Abstract: To provide a PLD having a reduced circuit area and an increased operation speed. In the circuit structure, a gate of a transistor provided between an input terminal and an output terminal of a programmable switch element is in an electrically floating state in a period when a signal is input to the programmable switch element. The structure enables the voltage of a gate to be increased by a boosting effect in response to a signal supplied from programmable logic elements, suppressing a reduction in amplitude voltage. This can reduce a circuit area by a region occupied by a booster circuit such as a pull-up circuit and increase operation speed.
