NON-VOLATILE MEMORY SYSTEM AND HOST COMMUNICATING WITH THE SAME

摘要

A nonvolatile memory system and a host communicating with the nonvolatile memory system are disclosed. A memory controller of the nonvolatile memory system according to an embodiment of the present invention can copy a mapping information group including logical-physical address mapping information of user data from a nonvolatile memory to a mapping information storage unit, and can transmit size information of the mapping information group to a host. The host according to an embodiment of the present invention can receive the size information of the mapping information group from the nonvolatile memory system, and can determine an order of commands to be transmitted to the nonvolatile memory based on the size information of the mapping information group.
