Claim 0:
1. An operating method of a solid state drive (SSD) comprising a nonvolatile memory, a link controller, and an SSD controller, the operating method comprising:
detecting a link to a host device;
receiving first biometric data via a user input receiving circuit in the SSD;
performing a comparison of second biometric data pre-stored in a biometric module with the first biometric data;
performing user verification based on a result of the comparison;
changing a state of the SSD controller from a lock state to an unlock state in response to a success of the user verification;
transmitting a trigger signal to the link controller when the state of the SSD controller transitions from the lock state to the unlock state; and
independently performing a relink to the host device without receiving a command indicating to perform the relink from the host device in response to the trigger signal being received by the link controller,
wherein the performing the relink to the host device includes deactivating and re-activating a data path to the host device.
