    • A nonvolatile latch circuit includes: a first gate part controlling to load or intercept an input signal based on a gate signal; a first logic gate functioning as an inverter or a gate outputting a constant voltage in response to the first control signal; a second logic gate functioning as an inverter or a gate outputting the constant voltage in response to the first control signal; a second gate part controlling to load or intercept the output of the second logic gate based on an inverted signal of the gate signal and sends the output of the second logic gate to an first input terminal of the first logic gate; and first and second injection type MTJ elements provided between the driving power supply and the first and second logic gates and changing in resistance depending upon a current flow direction.
    • 非易失性锁存电路包括:第一栅极部分,其基于栅极信号控制输入信号的加载或截取; 用作反相器的第一逻辑门或响应于第一控制信号输出恒定电压的栅极; 用作反相器的第二逻辑门或响应于第一控制信号输出恒定电压的栅极; 第二栅极部分,用于基于所述栅极信号的反相信号来加载或截取所述第二逻辑门的​​输出,并将所述第二逻辑门的​​输出发送到所述第一逻辑门的第一输入端; 以及设置在驱动电源和第一和第二逻辑门之间的第一和第二注入型MTJ元件,并根据电流流动方向改变电阻。
