A booting method of a main chip includes the following steps. The main chip searches a current block of a NAND Flash for reading a boot table from a current page of the current block and verifying a boot header of the boot table. When the boot header passes the verification, the main chip checks whether ID of the boot table and ID of the NAND Flash are the same. When the IDs of the boot table and the NAND Flash are the same, the main chip reads a next page of the current block and checks whether data stored in the current page and in the next page is the same. When the data stored in the current page and in the next page is the same, the main chip reads configuration information of the boot table to initialize the NAND Flash and boots.
