A method and a non-volatile memory apparatus for cloning prevention is provided. The non-volatile memory apparatus includes an Enhanced Media Identification (EMID) area, which is located in a specific area of the non-volatile memory, and stores an identification for identifying the non-volatile memory; and an EMID encoder for modifying the identification by a preset operation in conjunction with an arbitrary value, wherein the EMID area includes a first area in which reading by an external device is prevented, and a second area in which reading from the non-volatile memory by the external device is permitted in response to a read command.
