Abstract

The present invention relates to a memory management method of an embedded system. The embedded system has an electrically erasable programmable read-only memory (EEPROM) comprising a plurality of data sheets, each of which is stored with different data content. The method comprises: (a) labeling an item code and a status value on each data sheet of the EEPROM, wherein each item code represents the storage address in the data sheet of different data content, and the status value represents whether the data content is being corrected (the default value is non-writing status); (b) when the data content is to be corrected, changing the default value to writing status; (c) searching the data content of the storage address in accordance with the item code and refreshing the data content; and (d) resuming the status value to non-writing status.
