Abstract: PURPOSE: An apparatus and a method for allocation of memory block are provided to store only data on a read-only file in a block, of which the searched erasure number is greater, to prevent an additional writing operation even in the storage of a different new file or the operation of a garbage collector, thereby enhancing the overall performance of a flash memory. CONSTITUTION: A flash memory (200) includes a plurality of blocks. If the flash memory receives a request for the block allocation of a file, a memory controller (100) determines whether the file has a first attribute. If the file has the first attribute, the memory controller compares a size of the file with a size of each of the blocks. If the size of the file is larger than that of each of the blocks, the memory controller selects the first block. If data stored in the first block is not data having the first attribute, the memory controller moves the stored data to a second block, of which the erasure number is smallest.
