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.
