    摘要： To provide a semiconductor device including an RFID which can transmit and receive individual information without checking of the remaining charge of a battery or a replacing operation of the battery in accordance with deterioration over time of the battery for driving, and can maintain an excellent state for transmission and reception of individual information even when power of a radio wave or an electromagnetic wave from outside is insufficient. A battery (also described as a secondary battery) is provided as a power supply for supplying power to the RFID. Then, when power which is obtained from a signal received from outside is larger than predetermined power, its surplus power is stored in the battery; and when the power which is obtained from the signal received from outside is smaller than the predetermined power, power which is obtained from the battery is used for the power for driving.

    摘要： A liquid crystal display device with low power consumption is provided. In the liquid crystal display device having a source signal line driver circuit, a gate signal line driver circuit, a DAC controller, and a pixel portion and performing an image display using an n-bit (n is a natural number, n≧2) digital image signal, one pixel has memory circuits for storing an n-bit digital image signal and a D/A converter, and the n-bit digital image signal for one frame can be stored in the pixel. In case of a static image display, the image signal stored in the memory circuits is read out every frame to perform the display, and thus, only a DAC controller is driven during the display. Therefore, this contributes to a reduction of the power consumption of the entire liquid crystal display device.

    摘要： A memory circuit using a thin film transistor has been problems such as the drop in yield and the decrease in speed of response of the memory circuit due to variations in transistors. The purpose of the invention is to improve the yield and speed of the response of a memory cell by driving a word line by a voltage which is different from the logical amplitude of the memory cell. The invention is applicable to an SRAM, a DRAM, a mask ROM, and the like. A memory circuit of the invention is formed integrally with a display device for realizing a multi-functional display device.
