Abstract: Apparatuses and methods related to memory authentication. Memory devices can be authenticated utilizing authentication codes. An authentication code can be generated based on information stored in a fuse array of the memory device. The authentication code can be stored in the memory device. The stored authentication code can be compared to a captured authentication code based on fuse array information broadcast to memory components of the memory device. The authenticity of the memory device can be determined based on the comparison and can result in placing the memory device in an unlocked state.

Abstract: Systems and methods for read operations and management are disclosed. More specifically, this disclosure is directed to receiving a first read command directed to a first logical address and receiving, after the first read command, a second read command directed to a second logic address. The method also includes receiving, after the second read command, a third read command directed to a third logical address and determining that the first logical address and the third logical address correspond to a first physical address and a third physical address, respectively. The first physical address and the third physical address can be associated with a first word line of a memory component while the second logical address corresponds to a second physical address associated with a second word line of the memory component. The method includes executing the first read command and the third read command sequentially.

Abstract: Systems, apparatuses, and methods related to media management, including “garbage collection,” in memory or storage systems or sub-systems, such as solid state drives, are described. For example, a battery state associated with the memory system or sub-system may be used as an indicator or basis for managing a garbage collection operation on a data block. A controller or the system or sub-system may determine that a battery state or condition satisfies a criterion. Based on determining that the criterion is satisfied the, the garbage collection operation may be postponed until the battery state changes to satisfy a different battery condition.

Abstract: Systems, apparatuses, and methods related to media management, including “garbage collection,” in memory or storage systems or sub-systems, such as solid state drives, are described. For example, a signaling can be received that indicates a request from a controller to migrate valid data from a first data block to a second data block. For example, the first data block can be a data block of a plurality of memory cells configured as single-level-cell (SLC) memory. The second data block can be configured as multi-level-cell (MLC) memory. The data migration operation can include an error control operation that is performed using the memory component, the error control operation excluding transferring the data to the controller. The data can be migrated from the first data block configured as SLC memory to the second data block configured as MLC memory after the error control operation is performed using the memory component.

Abstract: Systems, apparatuses, and methods related to media management, including “garbage collection,” in memory or storage systems or sub-systems, such as solid state drives, are described. For example, a criticality value can be determined and used as a basis for managing a garbage collection operation on a data block. A controller or the system or sub-system may determine that a criticality value associated with performing a garbage collection operation satisfies a condition. Based on determining that the condition is satisfied, a parameter associated with performing the garbage collection operation can be adjusted. The garbage collection operation is performed on the data block stored on the memory component using the adjusted parameter.
