Summary:To suppress deterioration in reliability of data.SOLUTION: A memory system of one embodiment comprises a non-volatile memory that includes a plurality of groups each including a plurality of memory cells, and a memory controller. The memory controller is configured to, when a first temperature in writing processing in a first group and a second temperature after the writing processing in the first group satisfy a condition, execute refresh processing on the first group.SELECTED DRAWING: Figure 8 【課題】データの信頼性の悪化を抑制する。【解決手段】一実施形態のメモリシステムは、各々が複数のメモリセルを含む複数のグループを含む不揮発性メモリと、メモリコントローラと、を備える。メモリコントローラは、第１グループへの書込み処理における第１温度と、第１グループへの書込み処理の後における第２温度と、が条件を満たす場合、第１グループに対するリフレッシュ処理を実行するように構成される。【選択図】図８
