A system comprising:

• a memory device;
• and
• a processing device, operatively coupled with the memory device, to perform operations comprising:
• fetching, by the processing device, a first memory access command from a submission queue of a set of submission queues associated with a host system;
• populating, in one or more internal queues positioned between phases of an execution of the first memory access command, the first memory access command after processing by a preceding phase of the execution;
• and
• upon completion of the execution of the first memory access command, returning to the host system an indication of completion of the first memory access command.

A non-transitory computer-readable storage medium comprising instructions that, when executed by a processing device, cause the processing device to perform operations comprising:

• fetching, from a submission queue of a set of submission queues associated with a host system, a first memory access command;
• populating, in one or more internal queues positioned between phases of an execution of the first memory access command, the first memory access command after processing by a preceding phase of the execution;
• and
• upon completion of the execution of the first memory access command, returning to the host system an indication of completion of the first memory access command.
