The invention discloses a non-volatile Boolean logic architecture based on multi-voltage control of a magnetic tunnel junction. The device is characterized in that the device comprises a magnetic tunnel junction write-in circuit, reading and writing the shared magnetic tunnel pairs; a reading circuit and a fine voltage control circuit, the output end of the magnetic tunnel junction write-in circuit is connected with the first input end of the reading circuit through a read-write shared magnetic tunnel junction pair. The first output end of the fine voltage control circuit is connected with thepower supply voltage input end of the magnetic tunnel junction write-in circuit, and the second output end of the fine voltage control circuit is connected with the power supply voltage input end ofthe reading circuit. According to the invention, the reading and writing speed of the whole circuit can be improved, and the full non-volatility of the logic design and the simplified logic reading and output process of one-st
