ABSTRACT:
A nonvolatile memory has an erase table in which a free-space information flag is associated with each physical address of a memory area and an address translation table in which a physical address of a memory area is associated with each logical address. The free-space information flag indicates whether a corresponding memory area is permitted to be erased. A control circuit determines a memory area to which rewrite data is to be written by referring to the free-space information flag, reflects the physical address and the logical address of the memory area to which the data is written into the address translation table, and updates the free-space information flag. The memory area to which rewrite data is to be written is determined by referring to the free-space information flag, and rewriting is not performed in the same memory area.
