Abstract
A memory system includes a memory device including a plurality of memory arrays, each of which includes a plurality of memory blocks, and a controller suitable for setting super blocks each including respective memory blocks that belong to two or more memory arrays among the plurality of the memory arrays and performing a garbage collection operation on the super blocks based on a valid page information and a wearing level of each super block.
Claims20
A memory system, comprising:
- a memory device including a plurality of memory arrays, each of which includes a plurality of memory blocks;
- and
- a controller suitable for setting super blocks each including respective memory blocks that belong to two or more memory arrays among the plurality of the memory arrays and performing a garbage collection operation on the super blocks based on a valid page information and a wearing level of each super block.
A memory system, comprising:
- a memory device including a plurality of memory arrays, each of which includes a plurality of memory blocks;
- and
- a controller suitable for generating valid page information and bad block information for super blocks, each of which includes respective memory blocks that belong to two or more memory arrays among the plurality of the memory arrays, and determining reference values that are used for selecting a victim block for a garbage collection operation among the super blocks based on the valid page information and the bad block information.
A method for operating a memory system, comprising:
- generating valid page information and bad block information of super blocks, each of which includes respective memory blocks that belong to different memory arrays;
- determining reference values that are used for selecting a victim block for a garbage collection operation among the super blocks based on the valid page information and the bad block information;
- and
- performing the garbage collection operation on the super blocks based on the reference values.
