Abstract
A memory system according to the present embodiment includes a nonvolatile memory part storing an operating parameter required to perform a data read operation or a data write operation. A volatile memory part holds the operating parameter read out from the nonvolatile memory part after turning power on. A controller writes back the operating parameter in the volatile memory part to a first position of the nonvolatile memory part storing the operating parameter, based on number of times of power input to the volatile memory part, number of times of reading the operating parameter, or a read time of the operating parameter.
