Abstract
A semiconductor device that has reduced power consumption and is capable of non-destructive reading is provided. The semiconductor device includes a first circuit including a first transistor and a first FTJ element, and a second circuit including a second transistor and a second FTJ element. A first terminal of the first transistor is electrically connected to an output terminal of the first FTJ element, and a first terminal of the second transistor is electrically connected to an input terminal of the second FTJ element. A second terminal of the first transistor and a second terminal of the second transistor are electrically connected to a read circuit. In a data writing method, a voltage is applied between the input terminal and the output terminal of each of the first FTJ element and the second FTJ element to polarize the first FTJ element and the second FTJ element. In a data reading method, a differential current flowing through the first FTJ element and the second FTJ element is input to the read circuit.
