Zusammenfassung:To provide a memory system and an information processing system capable of easy failure analysis.SOLUTION: A memory system of an embodiment includes a controller which includes a non-volatile memory and a first memory and writes, into the first memory, log data including a history of a command for controlling the non-volatile memory. An information processing system of another embodiment includes a memory system and an information processor, and the information processor holds an expected value of the log data of the memory system and transmits, to the memory system, a signal instructing stop when a transmitted value of the log data transmitted from the memory system does not agree with the expected value.SELECTED DRAWING: Figure 9 【課題】不具合解析が容易であるメモリシステム及び情報処理システムを提供する。【解決手段】実施形態のメモリシステムは、不揮発性メモリと第１のメモリを含み、不揮発性メモリを制御するためのコマンドの履歴を含むログデータを第１のメモリに書き込むコントローラを備える。別の実施形態の情報処理システムは、メモリシステムと情報処理装置を備え、情報処理装置はメモリシステムのログデータの期待値を保持し、情報処理装置はメモリシステムから送信されてきたログデータの送信値が期待値と一致しない時、メモリシステムに停止を指示する信号を送信する。【選択図】図９
