A nonvolatile memory device has a nonvolatile memory and a memory controller for executing a read from the nonvolatile memory using a read option. The nonvolatile memory includes a plurality of memory space units (for example, a die described later), each memory space unit including a plurality of memory spaces (for example, a page). The memory controller holds management information in which a read option is recorded for each memory space unit that is a larger unit than a memory space in which units memory is read. The memory controller specifies a memory space unit including a read-source memory space, selects a read option corresponding to the specified memory space unit, and executes a read from the read-source memory space using the selected read option. |
