    • A flash memory is made to store a same boot program in a plurality of blocks in it. When a flash memory controller receives an access command for accessing the storage region storing the boot program from a CPU (Step S101), it outputs the read out data to the CPU only when the corresponding block is not faulty according to the determination (Steps S105, S106) made on the basis of the ECC contained in the data read out from the corresponding page and the determination (Step S109) made on the basis of the block information also contained in the data read out from the corresponding page. If, on the other hand it is determined that the block is faulty, the flash memory controller reads out the boot program stored in the next block (Steps S106, S103) and determines once again that the block is faulty or not faulty.
    • 闪速存储器将相同的引导程序存储在其中的多个块中。 当闪速存储器控制器从CPU接收访问存储引导程序的存储区域的访问命令时(步骤S101),仅当相应的块根据该确定没有故障时才将读出的数据输出到CPU(步骤 S 105,S 106),并且根据从相应页面读出的数据中还包含的块信息进行的确定(步骤S109),进行基于包含在从相应页面读出的数据中的ECC 。 另一方面,如果确定块有故障,则闪存控制器读出存储在下一块中的引导程序(步骤S106,S103),并再次确定该块是有故障的还是不存在的。
