Abstract
According to one embodiment, a memory system includes a nonvolatile memory and a controller. The nonvolatile memory includes blocks. The controller controls the nonvolatile memory. The controller acquires a write amount to the nonvolatile memory in a first period. The controller calculates an estimated amount of writing to the nonvolatile memory in the first period. The controller changes, when the write amount is larger than the estimated amount by a first threshold value or more, one or more parameters used for writing of data to the nonvolatile memory.
