Abstract:
A first non-volatile memory may store first data and a second non-volatile memory may store second data. An authentication component may be coupled with the first non-volatile memory and the second non-volatile memory and may receive a request to perform an authentication operation. In response to the request to perform the authentication operation, the authentication component may access the first data stored at the first non-volatile memory and the second data stored at the second non-volatile memory and determine whether the second data stored at the second non-volatile memory has become unreliable based on a memory disturbance condition. In response to determining that the second data stored at the second non-volatile memory has become unreliable, a corrective action associated with the first data stored at the first non-volatile memory may be performed.
