MEMORY SYSTEM AND OPERATING METHOD OF THE MEMORY SYSTEM

摘要

In a memory system including a memory device including a plurality of storage regions, and a controller suitable for selecting storage regions indicated by logical addresses from among the plurality of storage regions using a mapping table storing a plurality of pieces of mapping information for mapping a plurality of logical addresses to a plurality of physical addresses corresponding to the plurality of storage regions. The controller may narrow a search range in which a second requested logical address of N logical addresses (N is an integer greater than 2) is to be searched for in the mapping table based on a position in which the mapping information corresponding to a first requested logical address of the N logical addresses has been stored in the mapping table when the N logical addresses are sequentially searched for in the mapping table.

1. A memory system, comprising:
a memory device including a plurality of storage regions; and a controller suitable for selecting storage regions indicated by logical addresses from among the plurality of storage regions using a mapping table storing a plurality of pieces of mapping information for mapping a plurality of logical addresses to a plurality of physical addresses corresponding to the plurality of storage regions; wherein the controller narrows a search range in which a second requested logical address of N logical addresses (N is an integer greater than 2) is to be searched for in the mapping table based on a position in which the mapping information corresponding to a first requested logical address of the N logical addresses has been stored in the mapping table when the N logical addresses are sequentially searched for in the mapping table.
