Abstract
A nonvolatile memory device (101) includes a plurality of physical blocks, each of which is provide with a nonvolatile memory (103), a logic/physical address conversion table, a temporary block and a temporary table. The nonvolatile memory (103) includes a plurality of pages which are predetermined writing units, respectively. The logical-physical address conversion table (106) stores correspondence information between logic addresses and physical addresses of data to be stored in the physical blocks. The temporary block is a physical block to store data that are smaller in size than those of the page. The temporary table (107) stores correspondence information between logic addresses and physical addresses with respect to data to be stored in the temporary block.
