Abstract: The present disclosure relates to a storage device including a memory device to which a namespace including a plurality of zones is applied, a cache memory caching a media encryption key corresponding to each of a plurality of key tags, an encryptor encrypting data subject to a write request in response to a command input from a host by using a media encryption key corresponding to a key tag included in the command, and outputting encrypted data, and a write operation controller controlling the memory device to store the encrypted data in the memory device, wherein the media encryption key is a second media encryption key generated based on a first media encryption key provided from the host and a Root of Trust (RoT) generated from the encryptor.

Abstract: A transmitting and receiving circuit may include a first CMOS inverter configured to receive a first power supply signal and a first input signal. The transmitting and receiving circuit may include a first calculation amplifier including a non-inverted input terminal connected to an output terminal of the first CMOS inverter, and a first resistor connected between the output terminal of the first calculation amplifier and a first node. The output terminal of the first calculation amplifier and an inverted input terminal of the first calculation amplifier may be connected to each other. A first output signal may have a level smaller than that of the first input signal and may be output to the first node.

Abstract: A proximity sensor and a proximity sensing method using an event-based vision sensor are provided. The proximity sensor may include a point identification (ID) unit which identifies a point at which an output light output from a focused light source is reflected from an object in an image taken by the proximity sensor; and a distance determination unit which determines a distance between the object and the proximity sensor based on a position of the point.
