发明名称 Memory system
摘要 According to the embodiments, a memory system includes a nonvolatile semiconductor memory and a writing-loop-count monitoring unit that monitors a loop count of an applied voltage to the nonvolatile semiconductor memory required for data writing of the nonvolatile semiconductor memory as a writing loop count. Moreover, the memory system includes a management table for managing the writing loop count in block unit that is a unit of data erasing and a life managing unit that determines a degraded state of the nonvolatile semiconductor memory based on the management table.
