摘要： A semiconductor device in which a transistor using an oxide semiconductor containing In, Zn, or the like for a channel region can be driven like a p-channel transistor is provided. The semiconductor device includes a transistor and an inverter, wherein an output of the inverter is input to a gate of the transistor, a channel region of the transistor includes an oxide semiconductor film containing In, Zn, or Sn, and each channel region of transistors in the inverter contains silicon. When a high voltage is input to the inverter, a low voltage is output from the inverter and is input to the gate of the transistor, so that the transistor is turned off. When a low is input to the inverter, a high voltage is output from the inverter and is input to the gate of the transistor, so that the transistor is turned on.

摘要： An object is to provide a programmable logic device having logic blocks connected to each other by a programmable switch, where the programmable switch is characterized by an oxide semiconductor transistor incorporated therein. The extremely low off-state current of the oxide semiconductor transistor provides a function as a non-volatile memory due to its high ability to hold a potential of a gate electrode of a transistor which is connected to the oxide semiconductor transistor. The ability of the oxide semiconductor transistor to function as a non-volatile memory allows the configuration data for controlling the connection of the logic blocks to be maintained even in the absence of a power supply potential. Hence, the rewriting process of the configuration data at starting of the device can be omitted, which contributes to the reduction in power consumption of the device.

摘要： In a wireless tag with which a wireless communication system whose electric power of a carrier wave from a R/W is high, an overvoltage protection circuit is provided to prevent from generating excessive electric power in the wireless tag when the wireless tag receives excessive electric power. However, as noise is generated by operation of the overvoltage protection circuit, an error of reception occurs in receiving a signal whose modulation factor is small. To solve the problem, the maximum value of generated voltage in the wireless tag is held in a memory circuit after the overvoltage protection circuit operates, then the overvoltage protection circuit is controlled in accordance with the maximum value of generated voltage. The voltages at which the overvoltage protection circuit starts and stops operating are different from each other, and hysteresis occurs between the timing when the overvoltage protection circuit starts and stops operating.
