High-reliability interface circuit and method based on alternate bias

The invention relates to a high-reliability interface circuit structure and method based on alternate bias, and the high-reliability interface circuit structure and method based on alternate bias comprises: two redundancy modules, wherein the triple modular redundancy is carried out on a whole I2C interface system in each redundancy module; and a control module which is connected to the two redundancy modules and is used for controlling power supply switching and data transmission between the two redundancy modules. According to the high-reliability interface circuit based on alternate bias, two redundant modules are provided; triple modular redundancy is carried out on the whole I2C interface system in each redundancy module; and then, the power switching and data transmission between thetwo redundant modules are controlled by the control module, so that an annealing effect occurs in the semiconductor material under the condition that each redundant module is powered off, holes captured in the semiconductor
