Abstract
A memory system which includes a nonvolatile memory device configured to store a mapping table that includes a plurality of map segments each having mapping information between a logical address and a physical address; and a controller configured to: transfer the mapping information to a host through a host performance booster (HPB) operation based on a mode, which is selected by the host from a host control mode and a device control mode, and selectively request the host to change the mode between the host control mode and the device control mode based on a ratio of a read request with a physical address to all read requests, which are transferred from the host.
