Abstract: A method of operating a controller to decompress a compressed data file stored on a host computer, and store the resulting uncompressed data in a flash memory. The processor loads compressed data into random access memory (RAM) until a predetermined amount of compressed data is present in the RAM. The controller then decompresses compressed data retrieved from the RAM until a decompressed amount of decompressed data equals a block size corresponding to a minimum modulus size of the flash memory, where the minimum size block of data that can be written to the flash memory because of the design of the flash memory. The controller then transfers the block of decompressed data to the flash memory. These steps are repeated in a coordinated fashion until the entire compressed data file has been downloaded from the host computer, decompressed by the controller, and stored in the flash memory.
