PROBLEM TO BE SOLVED: To provide an electronic controller capable of readily and reliably rewriting data of each of a plurality of built-in processors without managing IDs of the processors.SOLUTION: In a plurality of electronic controller comprising a processor that has a rewritable non-volatile memory and executes a predetermined process according to data stored in the non-volatile memory, each of the processors extracts individual rewrite data that is included in an address range pre-assigned to itself from rewrite data that is transmitted from an external rewriting device; and rewrites the data that is stored in its own nonvolatile memory, with the individual rewrite data. |
