Abstract
According to one embodiment, a memory system includes a nonvolatile memory and a controller. The controller is connectable to a host, and is configured to control the nonvolatile memory. The controller is configured to write data to the nonvolatile memory using a plurality of write types with different data write speeds based on information provided by the host, and determine a write ratio of the plurality of the write types.
Claims24
A memory system comprising:
- a nonvolatile memory;
- and
- a controller connectable to a host and configured to control the nonvolatile memory, wherein
- the controller is configured to:
- write data to the nonvolatile memory using a plurality of write types based on information from the host, which is related to a write speed, the plurality of the write types have different data write speeds;
- when receiving a write command to which a parameter specifying the information is added from the host, determine a write ratio of the plurality of the write types in accordance with the information;
- and
- write data to the nonvolatile memory by mixing the plurality of the write types at the determined write ratio.
