STORAGE DEVICE PREVENTING LOSS OF DATA IN SITUATION OF LACKING POWER AND OPERATING METHOD THEREOF - A simplified explanation of the abstract

This abstract first appeared for US patent application 18196671 titled 'STORAGE DEVICE PREVENTING LOSS OF DATA IN SITUATION OF LACKING POWER AND OPERATING METHOD THEREOF

Simplified Explanation

The abstract describes a method and apparatus for preventing data loss in a storage device.

  • The method involves receiving a query plan from a host system, which specifies the necessary data to be stored in a volatile memory.
  • Based on the query plan, a data priority list is generated, which determines the importance of the necessary data.
  • When the main power supplied by the host system drops to or below a certain threshold, at least one portion of the volatile memory is selected.
  • The necessary data is then moved to the selected portion of the volatile memory, ensuring that it is not lost in case of power failure.


Original Abstract Submitted

The present disclosure provides methods and apparatuses for data loss prevention of a storage device. In some embodiments, the data loss preventing method includes receiving, from a host system, a query plan corresponding to necessary data to be stored in a volatile memory. The data loss preventing method further includes generating, based on the query plan, a data priority list corresponding to the necessary data. The data loss preventing method further includes selecting, based on the data priority list, at least one portion of the volatile memory, when a main power supplied by the host system drops to or below a power level threshold. The data loss preventing method further includes moving the necessary data to the at least one portion of the volatile memory.
