Abstract
A semiconductor device that has lower power consumption and is capable of non-destructive reading is provided. The semiconductor device includes first to fourth transistors and first and second FTJ elements. The first FTJ element and the second FTJ element each include an input terminal, a tunnel insulating film, a dielectric, and an output terminal. One of a source and a drain of the first transistor is electrically connected to one of a source and a drain of the third transistor, a gate of the fourth transistor, and the output terminal of the first FTJ element. One of a source and a drain of the second transistor is electrically connected to one of a source and a drain of the fourth transistor, a gate of the third transistor, and the output terminal of the second FTJ element.
