Abstract To provide a memory system capable of speeding up a memory system operation.SOLUTION: A memory system 1 comprises a non-volatile memory 20 including a first and a second page, and a memory controller 10 controlling a non-volatile memory. The memory controller performs a first write operation for the first page at a first time, performs a second write operation for the second page at a second time after the first time, and determines conditions of a second read operation for the second page performed after the first read operation on the basis of a time difference between the first time and the second time and a first history value indicating successful conditions of the first read operation for the first page performed after the first write operation.SELECTED DRAWING: Figure 1 【課題】メモリシステムの動作を高速化させるメモリシステムを提供する。【解決手段】メモリシステム1は、第1ページ及び第2ページを含む不揮発性メモリ20と、不揮発性メモリを制御するメモリコントローラ10と、を備える。メモリコントローラは、第1時刻に前記第1ページに対する第1書き込み動作を行い、第1時刻の後の第2時刻に第2ページに対する第2書き込み動作を行い、第1時刻と第2時刻との時間差と、第1書き込み動作よりも後に行われた第1ページに対する第1読み出し動作が成功した条件を示す第1履歴値と、に基づいて、第1読み出し動作の後に行われる第2ページに対する第2読み出し動作の条件を決定する。【選択図】図1
