Abstract:
A memory system includes a nonvolatile memory including memory dies, and a controller. The controller is configured to create a first virtual storage with a first part of the memory dies and a second virtual storage with a second part of the memory dies, and create a redundant logical domain spanning one or more memory dies corresponding to the first virtual storage and one or more memory dies corresponding to the second virtual storage. The memory controller is configured to, in response to a write command, store write data corresponding to the write command in a first region of the first virtual storage and in a second region of the second virtual storage, and return to the host a response including a first physical address of the first region and a second physical address of the second region.
