摘要： Disclosed is a storage device using non-volatile semiconductor memory that achieves high performance and long life for the device. When managing the non-volatile semiconductor memory (2), physical blocks are classified into three types: scratch blocks (22), data blocks (23), and erased blocks (24). Data writing from a host device (3) is performed on the scratch blocks. When the number of empty pages within a scratch block becomes less than a predetermined number or no longer exists, the block is treated thereafter as a data block, and one of the erased blocks is newly assigned as a scratch block. If there are insufficient erased blocks, a block with relatively less valid data is selected from among the data blocks. After copying all valid data included in the block to a scratch block, the block is erased, and thus an erased block is acquired.

摘要： A nonvolatile memory stores therein a plurality of partitioned translation tables which are created by partitioning a logical-to-physical address translation table in a page unit. A RAM stores therein a logical-to-physical address translation table cache for storing at least the one or more partitioned translation tables, a translation-table management table for managing the partitioned translation tables, and a cache management table for managing the logical-to-physical address translation table cache. The translation-table management table includes a cache presence-or-absence flag and a cache entry number, the cache presence-or-absence flag being used for indicating that the partitioned translation tables are stored into the logical-to-physical address translation table cache, the cache entry number being used for indicating storage destinations of the partitioned translation tables in the logical-to-physical address translation table cache. Reading/writing processings of information in the logical-to-physical address translation table between the nonvolatile memory and the RAM are performed in the page unit.
