OPERATION METHOD OF HOST DEVICE AND OPERATION METHOD OF STORAGE DEVICE: abstract simplified (18188882)

• This abstract for appeared for patent application number 18188882 Titled 'OPERATION METHOD OF HOST DEVICE AND OPERATION METHOD OF STORAGE DEVICE'

Simplified Explanation

This abstract describes a method for a host device to control a storage device. The host device receives initial mapping information from the storage device and performs an initial migration of source data from one region of the storage device to another region based on this information. The host device then receives first dirty information about first dirty data from the storage device and performs a first migration of this data based on the first dirty information. Similarly, the host device receives second dirty information about second dirty data and performs a second migration of this data based on the second dirty information. It is noted that the size of the first dirty information is different from the size of the second dirty information.

Original Abstract Submitted

An operation method of a host device configured to control a storage device includes receiving initial mapping information from the storage device, performing initial migration based on the initial mapping information such that source data present in a first region of the storage device migrate to a second region, receiving first dirty information about first dirty data of the source data from the storage device, performing first migration on the first dirty data based on the first dirty information, receiving second dirty information about second dirty data of the source data from the storage device, and performing second migration on the second dirty data based on the second dirty information, and a size of the first dirty information is different from a size of the second dirty information.
