PROBLEM TO BE SOLVED: To provide a flash memory control system capable of simply extending the life of a product and a method for controlling the flash memory control system by solving a problem that a conventional flash memory requires a logical/physical conversion table and requires the management of logical addresses and physical addresses and complicated management in writing frequency, erasing frequency, or the like. SOLUTION: In the flash memory control system and its control method, the flash memory includes an address management table for managing data start addresses, data lengths and data sorts, and when a writing request specifying a data sort is generated, the table is referred to, an unused address is specified as the start address of the data sort, the address management table is updated, and updated data are written in a different address in each time to extend the flash memory. It is also characterized that variable length data are successively written, and then these data are collectively rewritten in the newest data start address in each fixed erasing block.
