description To provide a control device and a control method capable of suitably performing refresh proceedings of a plurality of memory devices each having a NAND memory.SOLUTION: A control device that controls refresh proceedings of a plurality of memory device each having a NAND memory includes a confirming unit that confirms a content saved in the NAND memory in each memory device and a determining unit that determines a timing of the refresh proceeding of each memory device based on the result of confirming the saved content.SELECTED DRAWING: Figure 1 【課題】ＮＡＮＤメモリを有する複数のメモリデバイスのリフレッシュ処理を適切に行うことができる技術を提供する。【解決手段】ＮＡＮＤメモリを有する複数のメモリデバイスのリフレッシュ動作を制御する制御装置は、各前記メモリデバイスにおける前記ＮＡＮＤメモリの保存内容を確認する確認部と、前記保存内容の確認結果に基づき各前記メモリデバイスのリフレッシュ処理のタイミングを決定する決定部と、を備える。【選択図】図１
