Abstract
An electronic control unit includes: a nonvolatile memory capable of erasing data in units of erasure blocks and also writing data in units of write blocks smaller than the erasure blocks; and a processor. In response to a data rewrite request from outside, the processor of the electronic control unit erases data in a portion of the nonvolatile memory in units of erasure blocks and writes data into the portion of the nonvolatile memory in units of write blocks. The amount of data sent to the electronic control unit from outside is thereby decreased and the time needed to rewrite data in the nonvolatile memory is reduced.
