Abstract: A storage device includes a memory device and a controller. The memory device stores attribute information associated with a host memory buffer allocated on a host memory. The controller communicates with the host memory such that a plurality of pieces of data associated with operations of the memory device is buffered, based on the attribute information, in a plurality of host memory buffers allocated on the host memory. The controller communicates with the host memory such that first data corresponding to a first attribute group managed in the attribute information is buffered in a first host memory buffer among the plurality of host memory buffers and second data corresponding to a second attribute group different from the first attribute group is buffered in a second host memory buffer separate from the first host memory buffer.
