RS trigger based on MTJ device

The invention discloses an RS trigger based on an MTJ device, and relates to the technical field of integrated circuits. The invention aims to solve the problems of somersault and poor anti-interference capability in a traditional RS trigger. The RS trigger based on the MTJ devices comprises a double-channel pre-charging sensitive amplifier, a CMOS double-track circuit, two pairs of MTJ devices and two write-in circuits; the two write-in circuits are used for writing information into the two pairs of MTJ devices respectively, and the double-channel pre-charging sensitive amplifier reads information stored in the two pairs of MTJ devices through the CMOS double-track circuit. According to the invention, the two pairs of MTJ devices are combined with the CMOS circuit to realize an RS trigger function. The MTJ has the characteristic of non-volatility, and the content stored in the MTJ does not change in a reading stage. The write-in circuit is added to control the MTJ to switch between a write-in mode and a read
