Abstract: Methods, systems, and devices for coherency locking are described in which different types of writes have different coherency locking schemes. 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.

Abstract: Methods, systems, and devices for internal commands for access operations are described. A memory sub-system can receive a request to perform an access operation. A first core of the memory sub-system can generate an internal command for performing the access operation. The internal command can include information for storing in a reference queue of the memory sub-system and an identification of a command entry of the reference queue. The first core can issue the internal command to perform the access operation and a second core of the memory sub-system can store the information in the command entry of the reference queue.

Abstract: Methods, systems, and devices for caching identifiers for access commands are described. A memory sub-system can receive an access command to perform an access operation on a transfer unit of the memory sub-system.

In some embodiments, the memory sub-system can store the identifier in a shared memory that is accessible by the first core and can issue the internal command to perform the access operation on the memory sub-system.
