Abstract
According to one embodiment, a memory system includes an error mitigation encoder that executes error mitigation coding on write data to be stored in a processing target page of a non-volatile memory, a memory interface that writes the write data which has undergone the error mitigation coding in the processing target page of the non-volatile memory and reads the write data which has undergone the error mitigation coding from the processing target page as read data, an error mitigation decoder that performs error mitigation decoding on the read data read from the processing target page of the non-volatile memory, and an error mitigation coding rate deciding unit that decides an error mitigation coding rate of the error mitigation encoder and the error mitigation decoder on the basis of at least one of information indicating the processing target page and information indicating a device characteristic of the processing target page.
