摘要:
PURPOSE: A semiconductor integrated circuit and a processor are provided to reduce a leak current by saving data in an MTJ(Magnetic Tunnel Junction) and blocking power to a nonvolatile SRAM cell if a cache is not accessed. CONSTITUTION: A nonvolatile SRAM cell(10a) includes a first inverter(11), a second inverter(12), a first transistor(21), a second transistor(22), a third transistor(23), and an MTJ(31). One end of the first transistor is connected to a first bit line and the other end thereof is connected to a first input terminal of the first inverter. One end of a first device group is connected to a first output terminal of the first inverter and the other end thereof is connected to a second bit line. One end of a second device group is connected to the first inverter and the second inverter and the other end thereof is connected to the first terminal to which a preset potential is applied according to an operation.
