Low-latency processing for unmap commands

A host system, comprising:

• a controller configured to couple with a memory system, wherein the controller is configured to cause the host system to:
• transmit a plurality of commands comprising a set of unmap commands and one or more second commands of a type different than the set of unmap commands;
• receive a set of ready-to-transfer messages comprising a ready-to-transfer message for each unmap command of the set of unmap commands, wherein the set of ready-to-transfer messages are received consecutively;
• and
• transmit, in response to the set of ready-to-transfer messages, one or more messages comprising data for executing the set of unmap commands.

A non-transitory computer-readable medium storing code comprising instructions which, when executed by processing circuitry of a host system, cause the host system to:

• transmit, from the host system, a plurality of commands comprising a set of unmap commands and one or more second commands of a type different than the set of unmap commands;
• receive, at the host system, a set of ready-to-transfer messages comprising a ready-to-transfer message for each unmap command of the set of unmap commands, wherein the set of ready-to-transfer messages are received consecutively;
• and
• transmit, from the host system in response to the set of ready-to-transfer messages, one or more messages comprising data for executing the set of unmap commands.

A method, comprising:

• receiving, at the host system, a set of ready-to-transfer messages comprising a ready-to-transfer message for each unmap command of the set of unmap commands, wherein the set of ready-to-transfer messages are received consecutively;
• and
• transmitting, from the host system in response to the set of ready-to-transfer messages, one or more messages comprising data for executing the set of unmap commands.
