Abstract
Provided is a storage device with enhanced security. The storage device includes: a security pad; a non-volatile memory device; and a storage controller including a sensing pin connected to the security pad. The storage controller is configured to: classify data corresponding to an input/output request for the non-volatile memory device as hot data or cold data, based on an access frequency with respect to the data; encrypt write data to be stored in the non-volatile memory device; and perform a data protection operation of encrypting the hot data, based on a signal change at the sensing pin according to a change in electrical contact of a physical sensing structure, the physical sensing structure including the security pad and a locking structure. A locking structure in electrical contact with a security pad extends through a through hole defined in the substrate.
