  • Publication number: 20090089491
    Abstract: A semiconductor memory device comprises: a memory part which has a plurality of memory blocks having a memory cell capable of storing a plurality of different kinds of data which require a memory area having different characteristics, and a memory controller which has a function of treating each of the memory blocks as a deletion unit in order to manage the memory part and converting a logic address of the memory part to a physical address identifying the memory block, and which replaces the memory block with a preregistered free block in rewriting the memory block. The memory controller manages the different kinds of data to be stored in the memory part so as to store the same kind of data as before, even after each of the memories and free blocks in the memory part are rewritten.
