    Abstract: A request to retrieve user data stored at a memory device is received and a first error control operation associated with the user data is performed. An indication of a failure of the first error control operation is received, and in response, a subset of system data stored at the memory device is identified. A second error control operation is performed on the subset of the system data to retrieve the subset of the system data stored at the memory device, and the user data is read by using the subset of the system data retrieved based on the performing of the second error control operation.

    Abstract: Systems and methods are disclosed including a memory device and a processing device operatively coupled to the memory device. The processing device can perform operations comprising determining a data validity metric value with respect to a source set of memory cells of the memory device; determining whether the data validity metric value satisfies a first threshold criterion; responsive to determining that the data validity metric value satisfies the first threshold criterion, performing a data integrity check on the source set of memory cells to obtain a data integrity metric value; determining whether the data integrity metric value satisfies a second threshold criterion; and responsive to determining that the data integrity metric value fails to satisfy the second threshold criterion, causing the memory device to copy data from the source set of memory cells to a destination set of memory cells of the memory device.
