The host system may send, to the memory system, an indication that the data is to be written to the memory system, and the memory system may remove invalid data at the memory system until the memory system has sufficient resources to store the data.

The memory system may also create a restore point based on the memory system having sufficient resources and receiving the data. In other examples, the removal of invalid data at the memory system may be delayed until after the data is written to the memory system.
