Zusammenfassung:A method and system for memory management of a block-erasable flash-EProm. T he system comprises a FEProm manager and a file system. The FEProm manager manages memory allocation and deallocation of the FEProm. The file system is a hierarchical directory system and uses the FEProm manager to allocate and deallocate memory. In a preferred embodiment, the FEProm manager of the present invention provides for allocation of tree space, deallocation of allocated space, and reclamation of deallocated space in a block-erasable FEProm. Each block of the FEProm contains a block allocation structure, data regions, and free space. The block allocation structure contains an allocati on array which describes the allocation of the data region.
