Abstract: Provided is a method for operating a buffer cache which is performed by a storage device including a flash memory. The method includes converting a logical block address requested from a host into a logical page number. A region in which a page corresponding to the logical page number is located is searched for. A physical block address corresponding to the logical block address is generated with reference to a mapping table of the region in which the page corresponding to the logical page number is located. The searching for of the region includes searching for a look-up table having information about a region in which a plurality of pages of the flash memory are located.
