    Abstract: A burning system includes an indentifying module, a dividing module, a calculating module, an index module, and a burning module. The identifying module identifies bad blocks of the flash memory. The dividing module reads all blocks of the flash memory in sequence, and when one or more continuous blocks being read are bad blocks, groups the bad blocks and the previously read good block as a storage sector. The calculating module calculates a bad block ratio of each storage sector. The index module assigns a priority level to each storage sector according to the bad block ratio of the storage sector, and associates each priority level of the storage sectors with a start address. The burning module accesses the storage sectors in an order of the priority levels of the storage sectors, and begins writing programs into the storage sectors from the associated start addresses.
