Abstract
A boot method for a data control unit downloads boot information from a nonvolatile memory into a temporary buffer of a boot-activation unit. A processing unit is activated by the boot-activation unit; a boot code is executed by the processing unit; and an operating code is downloaded from the nonvolatile memory into a volatile memory through the boot-activation unit. To correct possible errors in the block of the nonvolatile memory containing information and boot codes, the boot-activation unit verifies whether the boot information downloaded into its volatile memory has a critical-error condition and activates a spare memory portion of the nonvolatile memory in presence of the critical-error condition.
