Method and System for Blending Data Reclamation and Data Integrity Garbage Collection

A non-volatile memory system, comprising:

• non-volatile memory;
• one or more processors;
• and
• memory storing one or more programs that, when executed by the one or more processors, cause the non-volatile memory system to perform operations comprising:
• determining occurrences of triggering events, wherein the triggering events include:
• data reclamation events, urgent data integrity recycling events, and scheduled data integrity recycling events, wherein the data reclamation events include events that each corresponds to the occurrence of one or more host data write operations in accordance with a target reclamation to host write ratio, a respective urgent data integrity recycling event occurs when a respective memory portion of the non-volatile memory system satisfies predefined urgent read disturb criteria, and the scheduled data integrity recycling events include events that occur at a rate corresponding to a projected quantity of memory units for which data integrity recycling is to be performed by the non-volatile memory system over a period of time;
• and
• in response to each of a plurality of triggering events, recycling data in a predefined quantity of memory units from a source memory portion to a target memory portion of the non-volatile memory system.

A non-transitory computer readable storage medium, storing one or more programs configured for execution by one or more processors of a non-volatile memory system, the one or more programs including instructions that when executed by the one or more processors cause the non-volatile memory system to perform operations comprising:

• determining occurrences of triggering events, wherein the triggering events include:
• data reclamation events, urgent data integrity recycling events, and scheduled data integrity recycling events, wherein the data reclamation events include events that each corresponds to the occurrence of one or more host data write operations in accordance with a target reclamation to host write ratio, a respective urgent data integrity recycling event occurs when a respective memory portion of the non-volatile memory system satisfies predefined urgent read disturb criteria, and the scheduled data integrity recycling events include events that occur at a rate corresponding to a projected quantity of memory units for which data integrity recycling is to be performed by the non-volatile memory system over a period of time;
• and
• in response to each of a plurality of triggering events, recycling data in a predefined quantity of memory units from a source memory portion to a target memory portion of the non-volatile memory system.
