Classification: CPC G | IPC G

Claim 8:
9. A solid state drive (SSD) connected to a host device comprising:
a nonvolatile memory;
a link controller configured to temporarily deactivate a data line while receiving power from the host device through a power line;
a user input receiving circuit configured to receive first biometric data from a user; and
an SSD controller configured to:
perform user verification by comparing second biometric data pre-stored in a biometrics module with the first biometric data received from the user input receiving circuit,
change a state of the SSD controller based on a result of the user verification,
transmit a trigger signal to the link controller in response to the state of the SSD controller changing from a lock state to an unlock state, and
independently perform a relink to the host device without receiving a command indicating the relink from the host device in response to the trigger signal being received by the link controller,
wherein when the SSD controller independently performs the relink, the link controller deactivates and re-activates the data line to the host device.
