摘要： The flash memory controller compresses data in response to a write request. On condition that there is a compression effect with respect to the compressed data, the flash memory controller writes the compressed data to the base area of a physical block of a flash memory. As physical pages assigned to the physical block, the flash memory controller reduces the physical pages assigned to the base area from 102 down to 59, and increases the physical pages assigned to the update area from 26 up to 69. Therefore, it is possible to suppress exhaustion of physical pages which are assigned to the update area, to reduce the number of erases of the physical block, and to consequently prolong device operating life.

摘要： A storage control apparatus comprises a storage unit, an association unit, and an execution unit. The storage unit stores association information showing multiple physical chunks which are configured in a physical address space of a nonvolatile semiconductor memory, multiple logical storage areas which are configured in a logical address space of the nonvolatile semiconductor memory, multiple logical chunks which are respectively associated with the multiple physical chunks, and an association between a logical storage area and a logical chunk. The association unit changes the association by changing the association information in accordance with a state of the nonvolatile semiconductor memory, and identifies based on the association information a physical storage area corresponding to a logical storage area specified in an input/output request from a computer. The execution unit executes the input/output request with respect to the identified physical storage area.

摘要： Logical-physical translation information comprises information denoting the corresponding relationships between multiple logical pages and multiple logical chunks forming a logical address space of a nonvolatile semiconductor storage medium, and information denoting the corresponding relationships between the multiple logical chunks and multiple physical storage areas. Each logical page is a logical storage area conforming to a logical address range. Each logical chunk is allocated to two or more logical pages of multiple logical pages. Two or more physical storage areas of multiple physical storage areas are allocated to each logical chunk. A controller adjusts the number of physical storage areas to be allocated to each logical chunk.
