PROBLEM TO BE SOLVED: To provide a semiconductor device capable of reducing power consumption.SOLUTION: A writing potential is supplied to a cell 11 in which data rewriting is to be performed, whereby data writing operation is performed. Meanwhile, in the cell 11 in which data rewriting is not to be performed, the data is transferred to a cell 12 and then rewriting operation is performed so that the transferred data is rewritten to the cell 11. As a result, the data stored in the cell 11 in which data rewriting is not to be performed can be maintained without the reading and writing operations in a driver circuit. It results in a higher rewriting speed and lower power consumption in the driver circuit. |
