Performance Optimization for Storing Data in Memory Services Configured on Storage Capacity of a Data Storage Device

A memory sub-system, comprising:

• a host interface operable on a connection to a host system according to a storage access protocol and a cache-coherent memory access protocol;
• a first memory configured to provide a non-volatile storage capacity of the memory sub-system, wherein at least a portion of the first memory is configured to implement a memory device attached via the connection to the host system;
• a second memory faster than the first memory;
• and
• a controller configured to:
• retrieve, from a queue, a command configured to identify a memory address in the memory device;
• and
• execute the command to store data into the memory device at the memory address.

A non-transitory computer storage medium storing instructions which, when executed in a computing system, cause the computing system to perform a method, comprising:

• establishing a connection between a host system and a memory sub-system, the connection operable according to a storage access protocol and a cache-coherent memory access protocol;
• attaching a first memory of the memory sub-system over the connection to the host system as a memory device accessible via the cache-coherent memory access protocol;
• entering, in a storage access queue, a command configured to identify a memory address in the memory device;
• and
• executing, by the memory sub-system, the command to store data into the memory device at the memory address.
