ABSTRACT:
A flash memory includes a data bank having a plurality of banks, a merge bank, and an update data bank. A file system using the flash memory includes a unit storing update data corresponding to a data rewrite command into the update data bank, a unit selecting the latest update data for each block from update data stored in the update data bank when the update data bank becomes full, and a processing unit processing the latest update data. The processing unit includes a unit storing latest update data into a merge bank, a unit selecting data associated with the latest update data from the data bank to store the selected data into the merge bank, and a unit setting the merge bank as a new data bank.
