Abstract
A request to program host data to a memory device of a memory sub-system is received. Redundancy metadata associated with the host data is generated. A determination is made, in view of the received request, whether the host data is valid data or invalid data. In response to a determination that the host data is invalid data, updated redundancy metadata associated with the host data is generated. The updated redundancy metadata indicates that the host data is invalid data. The host data and the updated redundancy metadata is programmed to the memory device.
