Abstract: A flash memory management method is provided. According to the method, when a request to write the predetermined data to a page to which data has been written is made, the predetermined data is written to a log block corresponding to a data block containing the page. When a request to write the predetermined data to the page again is received, the predetermined data is written to an empty free page in the log block. Even if the same page is requested to be continuously written to, the management method allows this to be processed in one log block, thereby improving the effectiveness in the use of flash memory resources.

Abstract: PURPOSE: A flash memory management method is provided to consistently restore the data at an emergency state, for example, an abrupt power shut-off, and to prevent a system performance from being lowered in an environment of a frequent data update on a specific page like a DOS file system based on a FAT(File Allocation Table). CONSTITUTION: The method comprises steps of receiving a request of a write operation on a page on which data has been recorded already, performing the write operation on a log block corresponding to a data block including the page, receiving again a request of a write operation on the same page, and performing the write operation on a free space within the log block. The log block is managed by a data structure of a log pointer table. Entries of the log pointer table include a logical address block, log_blk, a corresponding physical address block, phy_blk, of the data block, and logical addresses of corresponding pages within a corresponding log block in an order that the pages of the data block are recorded.
