The types of writes can be associated with different sources of write commands, such as external commands from a host system or internal commands from a garbage collection procedure. Coherency locking can be performed for external write commands received from a host system, while coherency locking is not performed for internal write commands. If an internal write is received for data that has been previously written at a prior location, a write to one or more physical memory devices can be performed and, once an acknowledgment is received that the write is complete, an update to a mapping table with the new location of the data is performed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Coherency locking schemes","description":"Methods, systems, and devices for coherency locking are described in which different types of writes have different coherency locking schemes.
