Abstract
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.
