A counter logic circuit is provided to reduce a circuit size and maintain stored data, even when a power supply is disconnected, by implementing the counter logic circuit using an MTJ(Magnetic Tunnel Junction). An MTJ includes magnetic guiding layers(112,114,116) and a resistance variation device(150). The resistance variation device includes a free magnetic layer(154) and a fixed magnetic layer(156). A direction of a magnetic induction current flowing through one of the magnetic guiding layer is determined by an input value. An insulation layer is arranged between the free magnetic layer(152) and the fixed magnetic layer. The MTJ(Magnetic Tunnel Junction) includes resistance read line pairs(172,174). The resistance read line pair reads the resistance values of the resistance variation device. |
