Abstract
According to one embodiment, a memory system includes a nonvolatile memory and a controller. The nonvolatile memory is correspond to a first mode of writing data of N bits per unit area and a second mode of writing data of M bits (M>N) per unit area. When receiving a first command issued prior to a write command to instruct writing write data to the nonvolatile memory, the controller selects one or both of the first mode and the second mode for writing the write data to the nonvolatile memory, to allow writing the write data to the nonvolatile memory to be executed in the first mode as much as possible, based on a capacity of the write data specified by the first command and a capacity of a free area of the nonvolatile memory.
