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 method for minimizing the degradation of performance upon accessing a flash memory using a logical-physical mapping scheme, and a method for efficiently storing and managing information on logical-physical mapping in a flash memory. A method for writing data in a flash memory includes determining whether a sector is empty in a physical page having a most recently written logical page number of data to be written, the offset of the sector matching that of the data to be written; if the sector is empty, writing the data in the sector to the physical page; and if the sector is not empty, selecting an empty physical page to write the data to a sector in the selected empty physical page of which the offset matches that of the data to be written and writing a logical page number for the data to the selected empty physical page.
