摘要： An object is to provide a memory device including a memory element that can be operated without problems by a thin film transistor with a low off-state current. Provided is a memory device in which a memory element including at least one thin film transistor that includes an oxide semiconductor layer is arranged as a matrix. The thin film transistor including an oxide semiconductor layer has a high field effect mobility and low off-state current, and thus can be operated favorably without problems. In addition, the power consumption can be reduced. Such a memory device is particularly effective in the case where the thin film transistor including an oxide semiconductor layer is provided in a pixel of a display device because the memory device and the pixel can be formed over one substrate.

摘要： To reduce a variation in the electrical characteristics of a transistor. A potential generated by a voltage converter circuit is applied to a back gate of a transistor included in a voltage conversion block. Since the back gate of the transistor is not in a floating state, a current flowing through the back channel can be controlled so as to reduce a variation in the electrical characteristics of the transistor. Further, a transistor with low off-state current is used as the transistor included in the voltage conversion block, whereby storage of the output potential is controlled.

摘要： Efficiency of a charge pump circuit is increased. The charge pump circuit includes serially connected fundamental circuits each including a diode-connected transistor and a capacitor. At least one transistor is provided with a back gate, and the back gate is connected to any node in the charge pump circuit. For example, the charge pump circuit is of a step-up type; in which case, if the transistor is an n-channel transistor, a back gate of the transistor in the last stage is connected to an output node of the charge pump circuit. Back gates of the transistors in the other stages are connected to an input node of the charge pump circuit. In this way, the voltage holding capability of the fundamental circuit in the last stage is increased, and the conversion efficiency can be increased because an increase in the threshold of the transistors in the other stages is prevented.
