MEMORY SYSTEM AND CONTROL METHOD |
| 摘要 |
According to an embodiment, a memory system includes multiple nonvolatile memories to/from each of which data can be written/read independently of one another; and a controller configured to control writing of data to and reading of data from the nonvolatile memories. Each of the nonvolatile memories includes a data storage including a normal data storage area for storing the data and a redundant data storage area for writing the data avoiding defect positions in the normal data storage area; and a defect information storage configured to store defect information indicating information on a defect of the data storage included in another nonvolatile memory different from the present nonvolatile memory. |

1. A memory system comprising:
multiple nonvolatile memories to/from each of which data can be written/read independently of one another; and a controller configured to control writing of data to and reading of data from the nonvolatile memories, wherein each of the nonvolatile memories includes:
a data storage including a normal data storage area for storing the data and a redundant data storage area for writing the data avoiding defect positions in the normal data storage area; anda defect information storage configured to store detect information indicating information on a defect of the data storage included in another nonvolatile memory different from the present nonvolatile memory. |
