Abstract
Abstract There is disclosed a method of updating data stored in storage locations of a storage unit, in particular of a Flash EPROM. The activity of updating data stored in some types of non-volatile storage units, such as Flash EPROMs, is time consuming. A remarkable reduction in updating time is obtained by writing information relative to updating to be carried out in not occupied storage locations and executing the updating all at once on the storage locations containing the data.
