Abstract
A novel semiconductor device or a highly reliable semiconductor device is provided. The on/off state of a transistor which functions as a switch for writing data is controlled using the potential of a potential hold portion. The potential of the potential hold portion is controlled using a plurality of capacitors, whereby both a positive potential and a negative potential can be held in the potential hold portion. Accordingly, deterioration of the transistor which functions as the switch for writing data can be prevented and the characteristics of the transistor can be maintained. Therefore, the highly reliable semiconductor device can be provided.
