Abstract
An electronic control unit includes a flash memory as a nonvolatile memory, which is capable of erasing its storage contents block by block, for storing control programs and data. An erasure processing is carried out for the storage content in each of the blocks identified by an erasure command received from an external device, and a rewrite processing is carried out to replace the erased content with a new content received from the external device. The number of the erasure processing is counted only once when the first one of the erasure commands is received for a plurality of blocks, as long as the control unit is held operative after its initial condition.
