ABSTRACT:
A file system created in a flash EEPROM memory array for an embedded system having a plurality of blocks of flash memory cells, each block being divided into identical-sized areas capable of being addressed, the file system including a data structure positioned at a predetermined one of the areas on each block of a flash EEPROM memory array, the data structure storing a logical identification of data stored in each of the areas, the logical identifications of data being stored sequentially in the physical order of the areas on the block, a controller implemented process for searching the predetermined ones of the areas on each block to detect a logical identification of data, and means for accessing the physical area associated with any logical identification of data which is detected.
