    摘要: An indexing method is based on a tree structure of a flash memory, which includes a plurality of pages. The indexing method stores an entry in the leaf node and an entry in an index node designating the leaf node, in the same page, and changes the maximum number of entries that are stored in the leaf node of the page and the maximum number of entries that are stored in the index node of the page on the basis of the number of entries in the leaf node and the number of entries in the index node, respectively.

    摘要: A storage device may include a main storage part including memories; and a controller configured to control an overall operation of the main storage part. The controller includes a filter manager configured to store data format information and a filtering condition provided from a host; stream filters configured to search and project data stored in the memories in parallel in response to a control of the filter manager to produce searched and projected data; and a merge filter configured to merge the searched and projected data of the stream filters in response to the control of the filter manager.

    摘要: Provided is a flash memory system supporting flash defragmentation. The flash memory system includes a host and a flash storage device. In response to a flash defragmentation command by the host, the flash storage device performs flash defragmentation by grouping fragments stored in fragmented blocks of a flash memory on a flash memory management unit basis. The flash memory management unit may be a memory block or page. The flash storage device performs the flash defragmentation regardless of the arrangement order of fragmented files stored in the flash memory.

    摘要: A method of managing meta data can be provided by generating log entry information including log data in response to changes to meta data that includes a plurality of groups of the meta data. A group of the meta data can be selected from among the plurality of groups of the meta data to provide a selected group of meta data in response to detecting that a number of pieces of the log entry information is equal to or greater than a particular threshold value. The selected group of the meta data and associated log data can be stored in a non-volatile memory device.
