ABSTRACT:
A memory management method for use in a portable computer to prolong the lifetime of an internal battery in the portable computer. The portable computer includes a non-volatile memory storage device. When the portable terminal is operating from the internal battery or cell, a recording operation is performed in an unused memory region and an address value of data to be deleted is registered in a delete queue, rather than being deleted at that time. Later, when the portable terminal is connected to an external power source, data to be deleted is deleted all at the same time, thereby reducing power consumption of the battery or cell in the portable computer. This method utilizes less capacity of the cell and prolongs operation time of the internal battery cell. Data can be recovered when a user desires recovery of the data unless the data corresponding to the address values recorded in the delete queue has already been deleted.
