Abstract
A method and apparatus control an operation mode of a storage device, including determining, by the storage device, an external power connection state of a host device connected to the storage device; and determining the operation mode of the storage device according to the determined external power connection state. The operation mode is determined to be a first mode when external power is connected to the host device and the operation mode is determined to be a second mode when the external power is not connected to the host device, where power consumption in the second mode being smaller than power consumption in the first mode.
Claims20
A method of controlling an operation mode of a storage device, the method comprising:
- determining, by the storage device, an external power connection state of a host device connected to the storage device;
- and
- determining the operation mode of the storage device according to the determined external power connection state, wherein the operation mode is determined to be a first mode when external power is connected to the host device and the operation mode is determined to be a second mode when the external power is not connected to the host device, power consumption in the second mode being smaller than power consumption in the first mode.
A storage device comprising:
- a connector electrically connecting a host device with the storage device and configured to transmit a first signal indicating an external power connection state of the host device to the storage device;
- and
- a processor configured to determine an operation mode of the storage device based on the first signal received through the connector and to control the storage device according to the determined operation mode,
- wherein the processor determines the operation mode of the storage device to be a first mode when the external power connection state indicates that external power is connected to the host device and determines the operation mode of the storage device to be a second mode, in which power consumption is smaller than in the first mode, when the external power is not connected to the host device.
A method of controlling an operation mode of a storage device, the method comprising:
- monitoring, by a host device connected to the storage device, a connection state of external power of the host device;
- determining whether the external power is connected to the host device based on the monitoring of the external power connection state;
- setting a first signal to a first logic state when the external power is determined to be connected to the host device, and setting the first signal to a second logic state when the external power is determined to be not connected to the host device;
- and
- transmitting the first signal to the storage device, wherein the operation mode of the storage device is determined based on the first signal.
