    • An XOR logic unit using a magnetic tunnel junction device using spin torque transform is provided to form a magnetization direction of a free magnetic layer identical to the magnetization direction of a pinned magnetic layer by controlling the flow of the current between an upper electrode and a lower electrode. An upper electrode(11) and a lower electrode(13) are comprised to pass electric current. An insulating layer(19) performs the electrical insulation between the upper electrode and the lower electrode. A free magnetic layer(17) and a pinned magnetic layer(15) are formed in the upper surface and the lower surface of the insulating layer. A current control circuit controls the flow of the current passing through between the upper electrode and the lower electrode. A sensing amplifier is connected to each one end of two magnetic memory cells.
