    • PURPOSE: A semiconductor device and a shift register reduce power consumption by controlling rewriting, storing, and reading of stored data of a capacitive element. CONSTITUTION: A logic circuit (101) receives a data signal through an input terminal. A capacitive element (102) includes a pair of electrodes, one of which is supplied with a power potential or a ground potential and the other of which is supplied with a potential of the input terminal of the logic circuit, so that data of the data signal is written as stored data. A transistor (103) controls rewriting, storing and reading of the stored data by controlling conduction between the input terminal of the logic circuit and the other of the pair of electrodes of the capacitive element. The off-state current per micrometer of a channel width of the transistor is lower than or equal to 100 zA.
    • 目的:半导体器件和移位寄存器通过控制电容元件的存储数据的重写,存储和读取来降低功耗。 构成:逻辑电路(101)通过输入端接收数据信号。 电容元件(102)包括一对电极,其中一个电极被提供有电源电位或地电位,另一个电极被提供给逻辑电路的输入端的电位,使得数据的数据 信号被写入存储数据。 晶体管(103)通过控制逻辑电路的输入端子与电容元件的一对电极中的另一个之间的导通来控制存储数据的重写,存储和读取。 晶体管的通道宽度每微米的截止电流低于或等于100zA。
