Abstract: Methods, systems, and devices for unmap backlog in a memory system are described. A memory system may be configured to support receiving an unmap command from a host system and signaling, to the host system, an indication that the unmap command has been processed (e.g., handled, acknowledged). In response to the unmap command, the memory system may proceed with various unmap operations, which may include unmapping at least some of the associated addresses after indicating that the unmap command has been processed. For example, a memory system may implement an unmap backlog table to identify sections of addresses that are to be unmapped (e.g., after indicating that the unmap command has been processed). In some examples, the memory system may support various aspects of prioritization between unmap operations (e.g., background unmap operations) and other access operations such as read operations, write operations, or other access operations.
