Abstract
A redundant data for substituting a sector in the second memory region for a damaged sector in the first memory region is stored in the 1088 sector of the flash memory (1), and a program-instruction for rewriting, the redundant data into the table RAM (7) and for writing a program instruction in a specific sector into a program RAM (3) is stored in the 0 sector of the flash memory (1). Because with this arrangement a separate redundant circuit is unnecessary, costs can be reduced.
