Abstract: This application provides a memory training method, a memory controller, a processor, and an electronic device. The memory controller keeps transmission delays of N DQs unchanged, adjusts a transmission delay of a DQS, and determines a maximum DQS transmission delay and/or a minimum DQS transmission delay of the DQS when all data carried in the N DQs is correctly transmitted. The memory controller adjusts the transmission delay of the DQS to a target DQS transmission delay between the maximum DQS transmission delay and the minimum DQS transmission delay. The method helps quickly align relative timing positions between the DQS and the N DQs. Therefore, memory training may be repeatedly performed in a working process of the processor, so that the N DQs keep long enough timing margins.
