Abstract
The present disclosure relates to a storage device. The storage device includes a memory device including write-completed blocks storing data and free blocks each containing no data and a memory controller controlling the memory device to perform a garbage collection operation to store valid data stored in a victim block, among the write-completed blocks, in one of the free blocks based on the number of map segments including mapping information between logical addresses and physical addresses of the valid data, and erase counts of the free blocks.
Claims20
A storage device, comprising:
- a memory device including write-completed blocks storing data and free blocks each containing no data;
- and
- a memory controller controlling the memory device to perform a garbage collection operation to store valid data stored in a victim block, among the write-completed blocks, in one of the free blocks based on the number of map segments including mapping information between logical addresses and physical addresses of the valid data, and erase counts of the free blocks.
A storage device, comprising:
- a memory device including a plurality of memory blocks;
- and
- a memory controller controlling the memory device to allocate a free block to store write data corresponding to a write request from a host, among free blocks each containing no data of the plurality of memory blocks, according to a size of data stored in the plurality of memory blocks and the number of map segments including mapping information between logical addresses and physical addresses of the data, and to store the write data in the free block in response to the write request.
