Abstract
The storage device includes multiple NAND devices each of which performs a process on the basis of a command; a command management unit that issues the command from a host to one of the NAND devices specified by the command and that sends an issue completion notification of the issued command to the host; and a state notifying unit that notifies, based on whether each of the NAND devices performs a predetermined process, the host whether each of the NAND devices is ready to accept the command. The host includes a NAND control unit that selects one of the NAND devices that is ready to accept the command based on the notification from the state notifying unit when the issue completion notification is received and sends, to the command management unit, a command to allow the selected one of the NAND devices to perform the process.
