A data holding circuit includes: a latch circuit having a first terminal and a second terminal, a logical value held at the first terminal being changed according to a value to be held by the data holding circuit, and the second terminal holding an inverted logical value of the logical value held at the first terminal; and a storing circuit which stores the logical values held at the first terminal and the second terminal in response to a write signal, and sets the logical values held at the first terminal and the second terminal to the stored logical values in response to a read signal, wherein the storing circuit includes two Magnetic Tunnel Junction elements which are connected in series between the first terminal and the second terminal and in reverse directions to each other.
