MEMORY SYSTEM |
| 摘要 |
According to one embodiment, a memory system includes a nonvolatile memory, a buffer memory, a power management unit, and a controller. The buffer memory is divided into a plurality of first subbuffers. The power management unit acquires a power consumption value. The power management unit starts and stops power supply to the first subbuffers with respect to each first subbuffer, based on the acquired power consumption value. The controller selects a second subbuffer from one or more third subbuffers being supplied with power. The controller buffers transfer data between the outside and the nonvolatile memory in the second subbuffer. |
