Abstract
A non-volatile memory (NVM) is to store data and a first password. The first password is to protect the data. A controller is to selectively enable interaction with the data based on authenticating the first password against a second password. A temporary region is to store the second password. The second password is discarded in response to a status change of the apparatus. The data, the first password, and the second password are resettable by the controller in response to a reset request to bypass the first password, such that the apparatus is restorable to an unused state without authenticating the first password.
Claims15
An apparatus comprising:
- a non-volatile memory (NVM) to store data and a first password, wherein the first password is to protect the data;
- a controller to selectively enable interaction with the data based on authenticating the first password against a second password;
- and
- a temporary region to store the second password;
- wherein the second password is discarded in response to a status change of the apparatus;
- and
- wherein the data, the first password, and the second password are resettable by the controller in response to a reset request to bypass the first password, such that the apparatus is restorable to an unused state without authenticating the first password.
An apparatus comprising:
- a non-volatile memory (NVM) to store data and a first password;
- a controller to selectively enable interaction with the data based on authenticating the first password against a second password;
- and
- a volatile storage to store the second password;
- wherein the data and the first password of the non-volatile memory are resettable by the controller in response to a reset request to bypass the first password, such that the memory module is restorable to an unused state without authenticating the first password.
A method, comprising:
- storing data in a non-volatile memory;
- storing a first password in the non-volatile memory;
- selectively enabling interaction with the data based on authenticating the first password against a second password;
- storing the second password in a temporary region;
- and
- resetting the data, the first password, and the second password in response to a reset request to bypass the first password, such that the memory module is restorable to an unused state without authenticating the first password.
