Timed data transfer between a host system and a memory sub-system

A memory sub-system, comprising:

• a plurality of media units capable of writing data concurrently;
• a local buffer memory;
• and
• at least one processing device configured to:
• receive a plurality of streams of write commands from a host system;
• identify one or more first media units among the plurality of media units, wherein the one or more first media units are identified to be available to write data from the plurality of streams concurrently with one or more second media units among the plurality of media units, wherein the one or more second media units are in progress of writing data;
• select one or more first commands from the plurality of streams for concurrent execution with one or more second commands that are in progress in the one or more second media units;
• initiate, in response to one or more first commands being selected for concurrent execution, communication of first data of the first commands from the plurality of streams from the host system to the local buffer memory of the memory sub-system;
• and
• execute the one or more first commands by storing the first data into the one or more first memory units, concurrently with the one or more second commands in progress in the one or more second media units;
• wherein the memory sub-system buffers, in the local buffer memory, no more than a predetermined number of units of data;
• the predetermined number corresponds to a number of media units in the memory sub-system that are capable of operating independent from each other in writing data;
• and each unit of data is no more than a maximum amount of data to be written in a media unit in response to a single write command.

A non-transitory computer storage medium storing instructions which, when executed in a memory sub-system, causes the memory sub-system to perform a method, the method comprising:

• receiving, in the memory sub-system, a plurality of streams of write commands from a host system;
• identifying a plurality of media units in the memory sub-system, wherein the plurality of media units are identified to be available to write data from the plurality of streams concurrently;
• selecting first commands from the plurality of streams for concurrent execution in the plurality of media units;
• initiating, by the memory sub-system and in response to the first commands from the plurality of streams being selected for concurrent execution in the plurality of media units, communication of first data of the first commands from the host system to a local buffer memory of the memory sub-system;
• wherein the memory sub-system buffers, in the local buffer memory, no more than a predetermined number of units of data;
• the predetermined number corresponds to a number of media units in the memory sub-system that are capable of operating independent from each other in writing data;
• and each unit of data is no more than a maximum amount of data to be written in a media unit in response to a single write command;
• and
• executing the first commands concurrently by storing the first data into the plurality of memory units.
