Abstract
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 EMID for identifying the non-volatile memory; and an EMID encoder for modifying the EMID by a preset operation in conjunction with an arbitrary value.
Claims19
A non-volatile memory for anti-cloning, comprising:
- an Enhanced Media Identification (EMID) area, which is located in a specific area of the non-volatile memory, and stores an EMID for identifying the non-volatile memory;
- and
- an EMID encoder for modifying the EMID by a preset operation in conjunction with an arbitrary value.
A method for authenticating a non-volatile memory for anti-cloning comprising:
- receiving a request an Enhanced Media Identification (EMID) from a host device by the non-volatile memory that stores an EMID for identifying the non-volatile memory in an EMID area located in a specific area of the non-volatile memory;
- modifying the EMID by a preset operation with an arbitrary value;
- and
- transmitting the modified EMID to the host device in response to the request.
