    Abstract: A storage device is configured to be connected to a host device via a physical cable which includes a power line and a data line. The storage device includes a non-volatile memory, a data path controller configured to temporarily deactivate the data line while power is supplied from the host device via the power line, and a memory controller. The memory controller includes a biometric module configured to receive biometric data and perform user authentication based on the biometric data; a biometric processing circuit configured to change a state of the memory controller, based on a result of the user authentication; and a data processing circuit configured to encrypt and decrypt data. The data path controller is configured to temporarily deactivate the data line in response to the changed state of the memory controller.

    Abstract: In a method of operating a storage device including a plurality of storage regions, a first request is received. The first request is for a cryptographic erasure with respect to a first storage region. During a first time interval, a first encryption key corresponding to the first storage region is changed based on the first request. A second request is received. In response to receiving the second request within the first time interval, a region access signal is outputted. In response to determining, based on the region access signal, that the second request is associated with the first storage region, an execution of the second request is held. In response to determining, based on the region access signal, that the second request is associated with a second storage region among the plurality of storage regions, the second request is executed.
