Semiconductor device including transistor with back gate, and memory device including the semiconductor device
The memory device includes a first transistor and a circuit. The circuit includes a second to a (2n+1)th transistor, a first to an n-th capacitor, a first wiring, and a first to an n-th retention node (n is an integer greater than or equal to 2). When n is 2, a memory cell MC[1] includes a transistor ROS[1], a transistor WOS[1], and a capacitor C[1] and a memory cell MC[2] includes a transistor ROS[2], a transistor WOS[2], and a capacitor C[2]. A back gate of the transistor WOS[1] and a back gate of the transistor WOS[2] are electrically connected to a wiring WBG. A bake gate of a first transistor, a back gate of the transistor ROS[1], and a back gate of the transistor ROS[2] are electrically connected to a wiring RBG.
