PROBLEM TO BE SOLVED: To provide a semiconductor device capable of retaining data for a long time.SOLUTION: The semiconductor device includes: first to third transistors; a fourth transistor having a first gate and a second gate; first to third nodes; a capacitive element; and an input terminal. A source of the first transistor is connected to the input terminal. A drain of the first transistor and a source of the second transistor are connected to the first node. A gate of the second transistor, a drain of the second transistor, and a source of the third transistor are connected to the second node. A gate of the third transistor, a drain of the third transistor, the capacitive element, and the second gate of the fourth transistor are connected to the third node.SELECTED DRAWING: Figure 1 |
