A memory management method for a portable terminal can prolong the lifetime of an internal battery in the portable terminal. The memory management method in a portable terminal using a non-volatile memory (27) is provided in which a recording operation is first performed in an unused memory region, an address value with respect to data to be deleted is registered in a delete queue, and then the data to be deleted is deleted all at a time when external power (22) is supplied, to thereby reduce power consumption of a cell (21) in a portable terminal using a limited capacity of the cell (21) and prolong an operation time of an internal cell (21). Data can be recovered when a user desires recovery of the data, unless the data corresponding to address values recorded in the delete queue is deleted all at a time. <IMAGE> |
