ABSTRACT:
A file system (10) for a memory device includes a first volume (12), a second volume (14), and a third volume (16). The first volume (12) is located at a highest portion of the memory space defined by the file system (10) of the memory device and includes a primary volume and directory entry control block area (18) to store the control blocks associated with the entire memory space of the memory device. Control blocks are stored in a descending order within the first volume (12). The second volume (14) is located at an intermediate portion of the memory space defined by the file system (10) and includes a secondary volume and directory entry control block area (20) to store the control blocks when the primary control block area (18) of the first volume (12) is being erased and rewritten into. The third volume (16) is located at a lowest portion of the memory space defined by the file system (10) and is used to store data files in an ascending direction.
