description A method of driving remapping in a flash memory, which is capable of writing the status of a block and a unit by reducing the number of partial write cycles as much as possible, and a flash memory architecture adapted thereto are provided. The remapping driving method includes searching for a predetermined physical unit based on mapping information about a predetermined block, searching the found physical unit for another block, the status of which is free, if the predetermined block exists in a valid state in the physical unit; changing the status of the other block into a status next to the status of the predetermined block, writing new data and additional information such as a logical block number to the other block, and changing the status of the predetermined block to a deleted state. Accordingly, the write status of a block or a unit can be managed for a flash memory having a restriction on the number of partial write cycles.
