Abstract: Disclosed is a method of copying data between open-channel solid state drives (SSDs), the method including transmitting, by a host, a read command to a source SSD, performing, by the source SSD, a read operation on data stored in the source SSD, in response to the read command, specifying, by the source SSD, an address of a data buffer of a destination SSD, in response to the read command, copying, by the source SSD, the stored data to the specified address of the data buffer, and storing, by the destination SSD, the data copied from the source SSD.

Abstract: Disclosed is a method of transceiving data using a physical page address (PPA) command on an open-channel solid state drive (SSD), the method including transmitting, by a host, a PPA command to a controller using a submission queue, and performing, by the controller, an operation based on the PPA command, wherein the PPA command includes an operation code (Opcode) to operate the controller and a PPA list for the controller to perform the Opcode on a memory, and the PPA list includes at least one PPA and bitmap information related to the at least one PPA.
