Abstract
A memory control system and method for controlling the rewriting of data in a flash memory which includes a boot memory portion having a plurality of sectors including a boot sector for storing cold boot data, N other boot sectors for storing other boot data and having a program process in each of said N boot sectors for rewriting data in boot sectors other than itself and other than said cold boot sector based upon the boot data stored therein. The control system further includes a boot data evaluation unit for recognizing which of the boot sectors has been most recently updated with update data and which program process is to be used for rewriting data in boot sectors other than itself and a rewrite unit for rewriting data.
