PURPOSE: A memory system and a memory mapping method thereof are provided to supply efficient data structure for mapping a logical sector in a physical memory, thereby reducing a memory size consumed in a mapping. CONSTITUTION: A memory control unit(120) provides data structure for mapping a logical address in a physical address on a nonvolatile memory(110). The memory control unit sets a representative value which is sequence data successively stored in a physical page block of serial physical addresses, for serial logical addresses of a logical page block corresponding to the physical page block. The memory control unit performs mapping between the logical addresses in the logical page block and the physical addresses in the physical page block by using the representative value.
