Abstract
According to one embodiment, a memory system includes a controller for controlling a data transfer between a nonvolatile memory and a host device. The controller writes, to the nonvolatile memory, management information to be used in the data transfer, a multiplexed pointer indicating a storage position, and a log indicating whether the writing of the pointer is successful, determines whether the multiplexing the pointer by the predetermined number is maintained according to at least one of the pointer and the log, and rewrites the multiplexed pointers to the nonvolatile memory when determining that the multiplexing the pointer by the predetermined number is not maintained.
