Abstract: A solid state drive (SSD) interface controller includes a host interface, first and second command interfaces, and an interface information storage unit. The interface information storage unit is configured to store information for determining activation or deactivation of each of the first and second command interfaces, and a capacity allocated to each of the first and second command interfaces. The interface information storage unit may comprise first and second registers storing interface information, which may be changed in response to an extension ROM BIOS executed during a booting operation. The command interfaces may be configured to communicate using interface protocols such as SATA, SATA express, or nonvolatile express. An interface power management unit may cut power to an interface when deactivated based on the stored interface information.

Abstract: A first storage device capable of performing peer-to-peer communications with a second storage device includes a first submission queue for storing a first operation code; a first completion queue for storing a first indication signal; and a first controller configured to, read the first operation code stored in the first submission queue, create a command including a second operation code based on the first operation code, issue the command to the second storage device, and receive and processes a second completion signal transmitted from the second storage device.
