Abstract
Viene proposto un metodo di aggiornamento di dati memorizzati in locazioni di memoria di una unità di memoria, in particolare di una memoria Flash EPROM.L'attività di aggiornamento di dati memorizzati in alcuni tipi di unità di memoria non volatili, quali le memorie Flash EPROM, è temporalmente dispendiosa.Una notevole riduzione nel tempo di aggiornamento viene ottenuta scrivendo informazioni relative all'aggiornamento da eseguire in locazioni di memoria non occupate ed eseguendo l'aggiornamento tutto in una volta sulle locazioni di memoria contenenti in una volta sulle locazioni di memoria contenenti i dati.
