Memory sub-system for supporting deterministic and non-deterministic commands based on command expiration and the state of the intermediate command queue

A method comprising:

• receiving a plurality of commands in a command queue, wherein the plurality of commands are directed to a plurality of memory components;
• scheduling the plurality of commands in the command queue, wherein scheduling the commands comprises, for each of the plurality of commands:
• determining an age of a command based on an entrance time of the command in the command queue,
• when the age of the command satisfies a first threshold,
• marking other commands in the command queue as not issuable when the command is a deterministic command, and
• marking other commands in the command queue as not issuable when the command is a non-deterministic command and the intermediate command queue is not empty, determining whether the command is a read command, and
• marking the command as not issuable when the command is a non-deterministic read command and the intermediate command queue is empty.

At least one non-transitory machine-readable storage medium comprising instructions that, when executed by a processing device, cause the processing device to perform operations comprising:

• receiving a plurality of commands in a command queue, wherein the plurality of commands are directed to a plurality of memory components;
• scheduling the plurality of commands in the command queue, wherein scheduling the commands comprises, for each of the plurality of commands:
• determining an age of a command based on an entrance time of the command in the command queue,
• when the age of the command satisfies a first threshold,
• marking other commands in the command queue as not issuable when the command is a deterministic command, and
• marking other commands in the command queue as not issuable when the command is a non-deterministic command and the intermediate command queue is not empty, determining whether the command is a read command, and
• marking the command as not issuable when the command is non-deterministic read command and the intermediate command queue is empty.
