UNMAP BACKLOG IN A MEMORY SYSTEM - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 17050334 Titled 'UNMAP BACKLOG IN A MEMORY SYSTEM'
Simplified Explanation
The abstract describes methods, systems, and devices for managing unmap commands in a memory system. When a host system sends an unmap command, the memory system acknowledges it and proceeds with unmapping the associated addresses. The memory system may use an unmap backlog table to keep track of the addresses to be unmapped. It also supports prioritization between unmap operations and other access operations like read and write operations.
Original Abstract Submitted
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.
