Controller command scheduling in a memory system to increase command bus utilization

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

• queue commands from a host, wherein the commands include a write command that uses a data bus, a send command that uses the data bus, and a read command that does not use the data bus;
• schedule the queued commands, wherein the send command is scheduled after the write command, and prior to the read command;
• determine that there is a conflict in usage of the data bus caused by scheduling the write and send commands;
• and
• in response to determining the conflict, change the scheduling to schedule the read command prior to the send command.

A method comprising:

• scheduling, by a controller, commands from a host, the commands including a write command, a send command, and a read command;
• determining a usage of a data bus based on the scheduling, wherein the send command is scheduled after the write command and prior to the read command;
• determining whether there is a conflict in the usage of the data bus, wherein the data bus is not available for transfer of data associated with the send command due to transfer of data associated with the write command;
• and
• in response to determining the conflict, changing the scheduling so that the read command is scheduled prior to the send command.
