    Abstract: A system includes a memory component and a processing device, operatively coupled with the memory component, to generate a physical presence security identification (PSID) for the memory component using a statistically random number generator. The processing device, operatively coupled with the memory component, can securely retrieve the PSID and revert the memory component to an original state using the PSID.

    Abstract: A method includes enabling a manufacturing mode at least partially based on a first signal provided via one of a number of reserved pins of an interface connector. The method can further include providing, in response to enabling the manufacturing mode, a second signal to a memory component coupled to the interface connector via a number of other pins of the interface connector.

    Abstract: A data erase operation is performed on the memory system. The directed data erase operation performed on the memory system erases blocks of the memory device including blocks that are indicated as not including user data. In some embodiments, a data erase operation may be performed on a memory system to erase those groups of memory cells (e.g., blocks) indicated as not including user data. In some embodiments, a data erase operation may be performed on a memory system to erase those groups of memory cells (e.g., blocks) indicated as valid without erasing those groups of memory cells (e.g., blocks) indicated as invalid. In some embodiments, a data erase operation that can be performed on a memory system may obtain information associated with failing scenes of groups of memory cells (e.g., blocks) prior to obtaining the information, and erase the blocks (e.g., invalid blocks) subsequently.

    Abstract: A determination is made by a processing device included in a memory component that an operation to program data to a location in the memory component has failed, the data is programmed to a different location in the memory component by the processing device upon determining the operation has failed, and a notification that the data has been programmed to the different location in the memory component is provided by the processing device to a processing device operatively coupled to the memory component.
