Electronic device with card interface

An electronic device that communicates with a storage device, the storage device comprising a plurality of connector pins comprising data pins and a power signal pin, the connector pins configured to be connectable to the electronic device,

• the electronic device comprising an interface,
• the interface configured to execute data transfer from the storage device to the electronic device using m number of data pins among the data pins (where m is a natural number) in a first operation mode,
• the interface configured to execute data transfer from the storage device to the electronic device using n number of data pins among the data pins (where n is a natural number greater than m) in a second operation mode,
• the interface configured to receive an operation mode information of the storage device, the operation mode information concerning the second operation mode,
• the interface configured to receive an operation voltage information concerning an operation voltage of the storage device,
• the interface configured to receive the operation mode information from the storage device via at least one of the connector pins, when a first command for reading the operation mode information is transmitted to the storage device via at least one of the connector pins,
• the interface configured to receive the operation voltage information from the storage device via at least one of the connector pins, when a second command for reading the operation voltage information is transmitted to the storage device via at least one of the connector pins,
• the interface configured to switch from the first operation mode to the second operation mode and from the second operation mode to the first operation mode in accordance with a selection by the electronic device.
