    • The present invention relates to an XOR logic operation apparatus using a spin torque transfer-based MTJ device. The XOR logic operation apparatus includes two parallel-connected magnetic memory cells (100, 200), and a sense amplifier (300) connected to first ends of the two magnetic memory cells. Each of the magnetic memory cells includes an MTJ device (10) and a current control circuit (50). Each magnetic memory cell includes a top electrode (11) and a bottom electrode (13) configured to allow current to flow therethrough, an insulating layer (19) configured to electrically insulate the top electrode from the bottom electrode, and a free magnetic layer (17) and a pinned magnetic layer (15) respectively formed on a top and a bottom of the insulating layer. The current control circuit controls flow of current passing between the top electrode and the bottom electrode, and changes a magnetization direction of the free magnetic layer.
    • 本发明涉及使用基于自旋转矩传输的MTJ装置的异或逻辑运算装置。 XOR逻辑运算装置包括两个并联的磁存储单元(100,200)和连接到两个磁存储单元的第一端的读出放大器(300)。 每个磁存储单元包括MTJ装置(10)和电流控制电路(50)。 每个磁存储单元包括被配置为允许电流流过其中的顶部电极(11)和底部电极(13),被配置为使顶部电极与底部电极电绝缘的绝缘层(19)和自由磁性层 17)和分别形成在绝缘层的顶部和底部上的钉扎磁性层(15)。 电流控制电路控制在顶部电极和底部电极之间流动的电流,并且改变自由磁性层的磁化方向。
