A method of rebooting a file system using a non-volatile memory is provided. The method comprising persistently storing critical information in the non-volatile memory, the critical information indicating a status of the file system; in response to a predetermined event, obtaining critical information of the file system stored in the non-volatile memory; determining if the file system has crashed based on the critical information; and rebooting from metadata in the non-volatile memory if it is determined that the file system has crashed.

Method of file system design and failure recovery with non-volatile memory

A storage device is disclosed, in which the device comprises memory () divisible into multiple zones, each zone comprising a plurality of physical blocks of the memory () and for associating with a zone-based address map for mapping between logical and physical addresses of said zone. The multiple zones are configurable independently of each other, and the memory () is non-volatile or volatile memory. A related zone-based block management and address mapping method, and a zone-based block management and address map for a storage device are also disclosed.
