    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: A touch sensor (touch panel) which can be formed over the same substrate as a display portion is provided. Alternatively, a touch sensor (touch panel) which does not cause degradation in the quality of an image displayed on a display portion is provided. The touch panel includes a light-emitting element and a microstructure in which a pair of electrodes facing each other is isolated with an insulating material. As the insulating material, an elastic material or a material having a hole is used so that a filler layer formed using the insulating material can be deformed when a movable portion operates. It is preferable to use a material which is softened or hardened by certain treatment (e.g., heat treatment or chemical treatment) after formation.

    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 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.
