Separate cores for media management of a memory sub-system

A method, comprising:

• calculating, by one or more controllers of a memory system, a likely rate at which a garbage collection procedure is performed on the memory system, wherein the likely rate is calculated based at least in part on a quantity of write commands received from a host device within a duration;
• selecting, by the one or more controllers, a first operational mode for performing the garbage collection procedure on the memory system, wherein the first operational mode is associated with a rate associated with the quantity of write commands received from the host device within the duration, wherein selecting the first operational mode is based at least in part on calculating the likely rate;
• identifying, by the one or more controllers, a trigger condition for initiating the garbage collection procedure on the memory system based at least in part on selecting the first operational mode;
• selecting, by the one or more controllers, one or more blocks of data associated with the garbage collection procedure based at least in part on a quantity of valid blocks of data;
• performing, by the one or more controllers, one or more first operations associated with a read process of the garbage collection procedure and the one or more blocks of data according to the first operational mode based at least in part on identifying the trigger condition;
• and
• performing, by the one or more controllers, one or more second operations associated with a write process of the garbage collection procedure and the one or more blocks of data according to the first operational mode based at least in part on performing the one or more first operations.

A method, comprising:

• selecting, by one or more controllers of a memory system, a first operational mode for performing a garbage collection procedure on the memory system, wherein the first operational mode is associated with a rate at which the garbage collection procedure is performed;
• identifying, by the one or more controllers, a trigger condition for initiating the garbage collection procedure on the memory system based at least in part on selecting the first operational mode;
• performing, by the one or more controllers, one or more first operations associated with a read process of the garbage collection procedure according to the first operational mode based at least in part on identifying the trigger condition;
• performing, by the one or more controllers, one or more second operations associated with a write process of the garbage collection procedure according to the first operational mode based at least in part on performing the one or more first operations;
• generating, by the one or more controllers, a plurality of write requests before identifying the trigger condition for initiating the garbage collection procedure;
• and
• storing, by the one or more controllers, the plurality of write requests to a queue of the memory system, wherein performing the one or more second operations associated with the write process of the garbage collection procedure is based at least in part on the plurality of write requests stored to the queue.

A memory system, comprising:

• one or more controllers, wherein the one or more controllers are operable to cause the memory system to:
• perform a first set of one or more operations associated with a read process of a first stage of a garbage collection procedure of the memory system, wherein the first set of one or more operations comprises issuing, from the one or more controllers to one or more queues of the memory system, a plurality of read commands in connection with the garbage collection procedure;
• and
• perform a second set of one or more operations associated with a write process of the first stage of the garbage collection procedure, wherein the second set of one or more operations comprises issuing a plurality of write commands in connection with the garbage collection procedure, wherein issuing, from the one or more controllers to the one or more queues, the plurality of read commands at least partially overlaps in time with issuing the plurality of write commands.

A memory system, comprising:

• one or more controllers, wherein the one or more controllers are operable to cause the memory system to:
• perform a first set of one or more operations associated with a read process of a first stage of a garbage collection procedure of the memory system, wherein the first set of one or more operations comprises issuing a plurality of read commands in connection with the garbage collection procedure;
• and
• perform a second set of one or more operations associated with a write process of the first stage of the garbage collection procedure, wherein the second set of one or more operations comprises issuing a plurality of write commands in connection with the garbage collection procedure, wherein each write command comprises an instruction to write at least one of a plurality of transfer units to a respective destination address of the memory system, wherein the plurality of write commands are issued in accordance with a write rate for the garbage collection procedure, and wherein at least one write command of the plurality of write commands is issued concurrent with issuing the plurality of read commands.
