    摘要： An object is to provide a semiconductor device with a novel structure, which can hold stored data even when not powered and which has an unlimited number of write cycles. A semiconductor device is formed using a material capable of sufficiently reducing the off-state current of a transistor, such as an oxide semiconductor material that is a widegap semiconductor. The use of a semiconductor material capable of sufficiently reducing the off-state current of a transistor allows data to be held for a long time. In addition, the timing of potential change in a signal line is delayed relative to the timing of potential change in a write word line. This makes it possible to prevent a data writing error.

    摘要： A semiconductor device with a novel structure and a driving method thereof are provided. A semiconductor device includes a non-volatile memory cell including a writing transistor including an oxide semiconductor, a reading p-channel transistor including a semiconductor material different from that of the writing transistor, and a capacitor. Data is written to the memory cell by turning on the writing transistor so that a potential is supplied to a node where a source electrode of the writing transistor, one electrode of the capacitor, and a gate electrode of the reading transistor are electrically connected, and then turning off the writing transistor so that a predetermined amount of electric charge is held in the node. In a holding period, the memory cell is brought into a selected state and a source electrode and a drain electrode of the reading transistor are set to the same potential, whereby the electric charge stored in the node is held.
