  • Patent number: 8949515
    Abstract: 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.

  • Patent number: 8909870
    Abstract: A storage device includes a non-volatile memory, a cache memory and a memory controller. The non-volatile memory stores a logical-to-physical address translation table for managing partitioned data and storage locations thereof. The cache memory stores a data cache and a logical-to-physical address translation table cache which holds a portion of the logical-to-physical address translation table. When the memory controller receives a data read-out request from outside, in the case no empty entry is found in the data cache, among the partitioned data in the data cache, it creates an empty entry to read out the data thereto by evacuating partitioned data of which entries in the logical-to-physical address translation table exist in the logical-to-physical address translation table cache into the non-volatile memory prior to other partitioned data.

  • Patent number: 8867075
    Abstract: A print data processing apparatus performs detection as to whether or not an identical resource is duplicated and described within print data. In a case where there is duplicated description, the duplicated resource is deleted from its second occurrence onward and the print objects are consolidated, the duplicated resources are deconstructed into individual resources and registered in a format that can be referenced in common from multiple print objects.

  • Patent number: 8760707
    Abstract: A print data processing apparatus process variable print data includes a cache unit, a determination unit, a determining unit, and a writing unit. The cache unit caches image data generated according to a drawing command included in the variable print data as cache data in a cache memory. The determination unit determines whether it is necessary to write the cache data in a secondary storage medium that is different from the cache memory. The determining unit determines cache data to be written in the secondary storage medium, in response to the determination unit determining that it is necessary to write the cache data in the secondary storage medium, based on a number of pages to be processed before each cache data cached in the cache memory is used next. The writing unit writes the cache data determined by the determining unit in the secondary storage medium.

  • Publication number: 20130275836
    Abstract: A storage device includes a nonvolatile memory, a volatile memory, and a memory controller. The volatile memory includes a free block management table, and a worn block management table. If the number of free blocks is equal to or larger than a threshold value 1, and errors of the number of equal to or larger than a threshold value 2 but smaller than a threshold value 3 are included in the data read from the nonvolatile memory, the memory controller registers the block in the worn block management table as a worn block. If the number of free blocks becomes smaller than the threshold value 1, the memory controller registers the worn block registered in the worn block management table in the free block management table as the free block.

  • Publication number: 20120215965
    Abstract: 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.
