SEMICONDUCTOR DEVICE |
摘要 |
A nonvolatile semiconductor device which can be driven at low voltage is provided. A nonvolatile semiconductor device with low power consumption is provided. A Schmitt trigger NAND circuit and a Schmitt trigger inverter are included. Data is held in a period when the supply of power supply voltage is continued, and a potential corresponding to the data is stored at a node electrically connected to a capacitor before a period when the supply of power supply voltage is stopped. By utilizing a change in channel resistance of a transistor whose gate is connected to the node, the data is restored in response to the restart of the supply of power supply voltage. |
