NVMe command completion management for host system memory

A method comprising:

• identifying an indication of a completion of a memory access command directed to a memory device;
• determining whether there are other memory access commands directed to the memory device that are pending;
• responsive to determining that there are other memory access commands that are pending and have not yet been completed, waiting for a threshold period of time to expire before sending the indication of the completion to a host system;
• responsive to determining that the threshold period of time has expired, coalescing additional indications of completions of the other memory access commands that have since completed and are available with the indication of the completion into a completion data chunk;
• and
• sending the completion data chunk to the host system, the host system to store the completion data chunk as one or more completion queue entries in a completion queue in a host memory of the host system via a single host memory write operation.

A system comprising:

• a memory device;
• and
• a processing device, operatively coupled with the memory device, to perform operations comprising:
• identifying an indication of a completion of a memory access command directed to the memory device;
• determining whether there are other memory access commands directed to the memory device that are pending;
• responsive to determining that there are other memory access commands pending, determining whether a size of the indication of the completion is smaller than a host memory write size granularity;
• responsive to determining that the size of the indication of the completion is smaller than the host memory write size granularity, appending dummy data to the indication of the completion to form a full completion data chunk;
• and
• sending the full completion data chunk comprising the indication of the completion and the dummy data to a host system.
