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: Embodiments of the inventive concept include computer-implemented method for shadowing one or more boot images of a mobile device. The technique can include duplicating boot images to shadow partitions in a user area of a non-volatile memory device such as a flash memory. The technique can include detecting boot image corruption, and causing a mobile device to boot from the shadow partitions. The technique can include dynamically shadowing and releasing blocks used by the shadow partitions. The technique can include boot failure recovery and bad image preservation through firmware flash translation layer (FTL) logical to physical mapping updates. Boot image corruption failures can be recovered from and/or debugged using the shadow partitions.
