Abstract

The invention discloses a data storage device, a data storage method and a storage system, and belongs to the technical field of memories. The data storage device disclosed by the invention comprises:a volatile storage unit which comprises a physical-to-logic address conversion mapping to be synchronized; a plurality of non-volatile memory cells including a synchronized logical-to-physical address translation map; and a cache controller which is respectively connected with the volatile storage unit and the plurality of nonvolatile storage units and is used for synchronizing the to-be-synchronized physical-to-logical address conversion mapping into the synchronized logical-to-physical address conversion mapping. The problems that an existing method for synchronizing the data in the volatile storage unit into the nonvolatile storage unit is complex in step and low in efficiency are solved.

Description

technical field [0001] The invention belongs to the technical field of memory, and in particular relates to a data storage device, a data storage method and a storage system. Background technique [0002] In the write operation program of the storage system, the memory serves as an important bridge between the controller and the hard disk, providing faster performance. However, if a sudden power failure occurs, how to protect the data in the memory from being lost is a commonplace in the storage system. topic. The volatile storage unit is when the computer is turned off or suddenly or accidentally turned off, the data inside will be lost, just like memory. The data in the non-volatile storage unit will not be lost under the above conditions, such as external storage such as hard disks. In addition, due to the limited storage space of the volatile storage unit, in order to permanently save the data in the volatile storage unit, it is necessary to It is necessary to synchron...
