Abstract
In a user setting information management method, when a predetermined event occurs, user setting information stored in the built-in memory of a portable telephone is read out and saved in a backup flash memory. When the predetermined event is canceled, the user setting information saved in the flash memory is written in the built-in memory of the portable telephone. The flash memory is divided into a plurality of independently erasable blocks. Each divided block is divided into a user setting information area for writing user setting information to be backed up and a block management area for writing block management information for each block. A user setting information log representing a backup order is generated as block management information for each block. Pieces of block management information of all blocks are compared every occurrence of a predetermined event to identify a block having undergone oldest backup and a block having undergone newest backup. After data in the block having undergone oldest backup is erased, data is backed up in the erased block. Block management information of the erased/backup block is written in the block having undergone newest backup. A user setting information management system is also disclosed.
