    摘要: Probability of malfunction of a semiconductor storage device is reduced. A shielding layer is provided between a memory cell array (e.g., a memory cell array including a transistor formed using an oxide semiconductor material) and a peripheral circuit (e.g., a peripheral circuit including a transistor formed using a semiconductor substrate), which are stacked. With this structure, the memory cell array and the peripheral circuit can be shielded from radiation noise generated between the memory cell array and the peripheral circuit. Thus, probability of malfunction of the semiconductor storage device can be reduced.

    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.
