The memory cell array, in which memory cells are arranged in a matrix, includes first signal electrodes, second signal electrodes which are arranged in a direction so as to intersect the first signal electrodes, and a ferroelectric layer disposed at least at intersection regions between the first signal electrodes and the second signal electrodes. The peripheral circuit section includes circuits for selectively allowing information to be written into or read from the memory cells, such as a first driver circuit, a second driver circuit, and a signal detection circuit. The memory cell array and the peripheral circuit section are disposed in different layers so as to be layered. This ferroelectric memory device can significantly increase the degree of integration of the memory cells and decrease the chip area.

摘要： A matrix liquid crystal display circuit includes a selecting transistor connected to the picture element and a capacitor for each picture element of the matrix. The other picture element and capacitor terminals connect to common electrodes and the transistor gates in each row connect to a common electrode. In each column a common source line connects to the sources of the transistors and a signal sampling circuit periodically applies an image signal to the source line of each column in sequence. No amplification is used between the sampling circuit and the transistor sources. Metallic leads serve as the source lines, but other circuits and components are integrated on a common substrate.

摘要： A liquid crystal display device wherein display elements are arranged in a matrix display on a substrate and the display is driven in response to external display signals is provided. The display device includes a thin film layer having a rugged diffusing surface and an opposed transparent electrode plate spaced apart from the thin film layer. A guest-host liquid crystal material including a pleochroic dye is utilized. The thin film layer may be a metal film such as, aluminum, an aluminum alloy, silver or a silver alloy having a rugged surface for providing a diffused white surface formed by vaccum evaporation, sputtering, heat-treatment, recrystallization or etching.
