Abstract
A memory system may comprise: a memory device including a plurality of memory dies; and a controller including a first memory, Wherein the controller may store data segments of user data, corresponding to a plurality of commands received from a host, in the first memory, controls the memory device to sequentially store the data segments in the memory dies through interleaving, may update map segments of map data corresponding to storage of the data segments in the memory dies, may store the map segments in the first memory, controls the memory device to store the map segments stored in the first memory in the memory dies, and may assist the host in storing the map segments, stored in the first memory, in a second memory in the host.
Claims22
A memory system comprising:
- a memory device including a plurality of memory dies;
- and
- a controller including a first memory,
- wherein the controller stores data segments of user data, corresponding to a plurality of commands received from a host, in the first memory, controls the memory device to store the data segments in the memory dies,
- updates map segments of map data corresponding to storage of the data segments in the memory dies and stores the updated map segments in the first memory,
- assists the host to store the updated map segments to a second memory in the host, and
- wherein the controller controls the memory device to store the map segments, stored in the first memory, in the memory dies.
A method for operating a memory system, comprising:
- receiving a plurality of commands from a host, for a memory device including a plurality of memory dies;
- storing data segments of user data, corresponding to the commands, in a first memory included in a controller of the memory device, and storing the data segments in the memory dies;
- updating map segments of map data corresponding to storage of the data segments in the memory dies, and storing the updated map segments in the first memory;
- storing the updated map segments in a second memory included in the host;
- and
- storing the map segments stored in the first memory, in the memory dies.
