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.
Claims20
A memory system comprising:
- a nonvolatile memory including blocks;
- and
- a controller configured to control the nonvolatile memory,
- wherein the controller is configured to:
- acquire a write amount to the nonvolatile memory in a first period;
- calculate an estimated amount of writing to the nonvolatile memory in the first period;
- and
- change, 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.
A control method of a memory system comprising a nonvolatile memory including blocks, the method comprising:
- acquiring a write amount to the nonvolatile memory in a first period;
- calculating an estimated amount of writing to the nonvolatile memory in the first period;
- and
- changing, 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.
