To provide an automobile electronic controller capable of shortening the update time of software stored in a non-volatile memory.SOLUTION: An automobile electronic controller 10 has a non-volatile memory 13 that can erase data in units of erasure blocks EB1-EBq and write data in units of write blocks WB1, WB2, ..., WBx equal to or smaller than the erasure block, so that a control program is stored in each storage area configured in units of integer multiples of the erasure block in the non-volatile memory. In response to a rewrite request from an external, part of data of the non-volatile memory is erased in units of the erasure blocks. When writing data in units of the write blocks to the non-volatile memory, rewrite correctness is confirmed for each of the blocks.SELECTED DRAWING: Figure 5

    【課題】不揮発性メモリに記憶されたソフトウェアの更新時間を短縮できる自動車用電子制御装置を提供する。【解決手段】自動車用電子制御装置10は、消去ブロックEB1〜EBq単位でデータを消去可能であると共に、消去ブロックと同一又は小さい書込ブロックWB1,WB2,…,WBx単位でデータを書込み可能な不揮発性メモリ13を有し、該不揮発性メモリにおける消去ブロックの整数倍の単位で構成された記憶領域毎に制御プログラムが記憶される。そして、外部からの書換え要求に応じて、不揮発性メモリの一部のデータを消去ブロック単位で消去し、不揮発性メモリに書込ブロック単位でデータを書込む際に、該ブロック毎に書換えの正誤を確認することを特徴とする。【選択図】図5
