Abstract
According to one embodiment, a storage system includes a first storage including first nonvolatile memories storing data which is corrupted when data is read from the first nonvolatile memories, and a controller which controls the first storage. The controller reads data from a first nonvolatile memory at a first address, and determines that whether the read data is to be written back to the first storage or not.
Claims14
A storage system comprising:
- a first storage which includes first nonvolatile memories storing data which is to be corrupted when data is read from the first nonvolatile memories;
- and
- a second storage which includes second nonvolatile memories storing data in a nonvolatile manner;
- and
- a controller which controls the first and second storages,
- wherein the controller is configured to:
- read data from a first nonvolatile memory at a first address;
- determine whether the read data is to be written back to the first storage or not;
- write the read data to a second nonvolatile memory at a second address in the second storage, if it is determined that the read data is not to be written back to the first storage;
- and
- write the read data to a first nonvolatile memory at a third address in the first storage, if it is determined that the read data is to be written back to the first storage.
