An apparatus includes a Replay Protected Memory Block (RPMB) formed in a plurality of non-volatile memory cells. Control circuitry is configured to authenticate access to the RPMB with a plurality of keys. Authentication of write access to the RPMB is through a write key and authentication of read access to the RPMB is through a read key.
