    摘要: An apparatus and method for reorganizing mapping information in a flash memory are provided. The apparatus includes a sector-managing module that secures a mapping sector where mapping information is recorded in a physical unit, and determines whether user data is recorded up to a sector located in a predetermined position, and a mapping-information-recording module that records the mapping information in the mapping sector according to a result of the determination. Here, the mapping information includes a relation of a physical sector storing the user data and a logical sector corresponding to the physical sector.

    摘要: A method of re-mapping a flash memory, which minimizes the number of times the flash memory, is accessed and helps to evenly use the entire area of the flash memory, is provided. The method includes arranging a plurality of physical units yet to be mapped according to their erase count values, and sequentially mapping the physical units to a logic unit in such a manner that a physical unit having a smaller erase count value is mapped to the logic unit ahead of a physical unit having a larger erase count value.

    摘要: A data management device and a data management method for a flash memory, in which physical addresses are classified according to pages, each of which is a physical data operation unit, and a predetermined data operation is performed with respect to the classified physical addresses. The data management device and method reduce time required for the data operation in a large-block flash memory, in which a physical data operation unit is larger than a logical data operation unit. As a result, an optimal data operation can be achieved in a large-block flash memory.
