    Abstract: A management method for a memory system executes a first memory system management sequence upon determining that the memory system was normally powered off, and a second sequence upon determining that the memory system was abnormally powered off. The first sequence allows immediate execution of a program operation at a valid data page location extracted from stored metadata, while the second sequence allows execution of a program operation only after programming dummy data to at least one erroneous page.

    Abstract translation: 存储系统的管理方法在确定存储器系统正常断电时执行第一存储器系统管理序列,并且在确定存储器系统异常断电时执行第二序列。 第一序列允许在从存储的元数据提取的有效数据页位置处立即执行程序操作,而第二序列仅允许在将伪数据编程到至少一个错误页面之后执行编程操作。

    Abstract: A nonvolatile storage device in accordance with the inventive concepts includes a nonvolatile memory device comprising a first memory area, a second memory area, and a memory controller. The memory controller includes a first register configured to store reliable mode information, and a second register configured to store operating system (OS) image information. The memory controller is configured to receive a command from a host based on the reliable mode information; determine whether the command is a write request for an OS image and whether OS image information accompanying the command matches the OS image information stored in the second register; write the OS image to the first memory area if the OS image information accompanying the command matches the OS image information stored in the second register, and block data migration of the OS image from the first memory area to the second memory area.

    Abstract translation: 根据本发明构思的非易失性存储设备包括非易失性存储器件,其包括第一存储区域,第二存储器区域和存储器控制器。 存储器控制器包括被配置为存储可靠模式信息的第一寄存器和被配置为存储操作系统(OS)图像信息的第二寄存器。 存储器控制器被配置为基于可靠模式信息从主机接收命令; 确定该命令是否是针对OS映像的写请求以及伴随命令的OS映像信息是否与存储在第二寄存器中的OS映像信息相匹配; 如果伴随命令的OS图像信息与存储在第二寄存器中的OS图像信息相匹配,并将OS图像从第一存储区块移动到第二存储区域,则将OS图像写入第一存储器区域。
