Abstract
A storage device includes a main storage and a storage controller to control the main storage. The main storage stores data and includes a plurality of nonvolatile memory devices. The storage controller loads at least one of (a) at least a portion of mapping tables and (b) at least one of a portion of directories to a host memory buffer included in an external host device, based on at least one of a size of the host memory buffer and locality information associated with a data access pattern of the host device. The mapping tables are stored in the nonvolatile memory devices and the mapping tables indicate a mapping relationship between a physical address and a logical address of corresponding ones of the nonvolatile memory devices. The directories store address information of the mapping tables.
