<p><P>PROBLEM TO BE SOLVED: To provide an effective data storage method and data reading method when using a NAND type flash memory as an image data storage means of a game machine. <P>SOLUTION: The NAND type flash memory 29 is constituted of a plurality of data blocks and, when there is a defective data block in the plurality of data blocks, the next image data of image data stored in a data block immediately before the defective data block are stored in the data block immediately after the defective data block for avoiding the defective data block, and a mediation circuit 28, in response to an image data reading request from a VDP (Video Display Processor) 24, converts the head address of the image data stored in the data block after the defective data block into the next address of the last address of the image data stored in the data block before the defective data block and outputs it. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
