Signal transmission circuit and method thereof, memory and electronic equipment

The embodiment of the invention provides a signal transmission circuit and method, a memory and electronic equipment, the signal transmission circuit comprises a plurality of main transmission units and a plurality of redundant transmission units, and each main transmission unit and the adjacent transmission units in the target direction form a transmission path group; the signal transmission circuit further comprises: a transmission control circuit configured to receive the failure information and output a repair control signal based on the failure information; and a repair control circuit configured to control the plurality of transmission path groups to perform signal transmission path repair processing based on the repair control signal so as to keep the main transmission unit executing the signal transmission function in the transmission path groups unchanged, or the main transmission unit used for executing signal transmission in the transmission path group is switched to the adjacent transmission unit
