摘要： It is an object to give excellent data retention characteristics to a semiconductor device in which stored data is judged in accordance with the potential of a gate of a specified transistor, by achieving both reduction in variation of the threshold voltage of the transistor and data retention for a long time. Charge is held (data is stored) in a node electrically connected only to a source or a drain of a transistor whose channel region is formed using an oxide semiconductor. There may be a plurality of transistors whose sources or drains are electrically connected to the node. The oxide semiconductor has a wider band gap and a lower intrinsic carrier density than silicon. By using such an oxide semiconductor for the channel region of the transistor, the transistor with an extremely low off-state current (leakage current) can be realized.

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.
