The invention discloses a memory data read-write method and system and a memory controller. In the application, when the memory controller needs to write data into a channel group, the memory controller obtains target data; and calling an ECC algorithm to generate a check code of the target data, wherein the check code is used for checking and correcting the target data. The memory controller writes target data and a check code into a channel group, the target data being stored in channels of the channel group in a dispersed manner. The check codes are stored in each channel of the channel group in a distributed manner. According to the method, the memory particles capable of storing the check codes exist in each channel group, the check codes of the target data are dispersedly stored in the memory particles for storing the check codes in each channel, the number of the memory particles for storing the check codes of the target data is large, the data size of the check codes is large, and it is guaranteed tha
