摘要
A method for initializing and operating a flash memory file system and a computer-readable medium storing a program adapted to perform the method are disclosed. The method includes programming the flash memory file system in order to conceptually divide logical blocks into logical groups, and storing erasure data for one of the logical groups in a first region of a meta block. The method also includes loading erasure data for one logical group into an external memory device and mapping the logical blocks of the current logical group to the physical blocks in accordance with the erasure data loaded into the external memory device. The method also includes storing data of a data file in a data block of a flash memory device in accordance with the mapping of the logical blocks to the physical blocks.
