Dynamic storage method, device and system

The invention relates to the technical field of storage, in particular to a dynamic storage method, device and system. The dynamic storage method and device are applied to a memorizer. The dynamic storage system comprises the memorizer, a processor and the dynamic storage device, wherein the dynamic storage device comprises an establishing module, a first writing module and a second writing module, the establishing module is used for establishing at least one address zone and at least one data zone, each data zone corresponds to one address, the first writing module is used for cyclically writing an address of one data zone where data is to be stored in the corresponding address zone at intervals of first predetermined time, and the second writing module is used for cyclically writing data in the corresponding data zone according to the address written into the address zone at intervals of second predetermined time. By adopting the scheme, each sector of the memorizer is used averagely to prolong the service
