Periodic flush in memory component that is using greedy garbage collection

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

• identifying a first block of a plurality of blocks stored at a first memory based on an amount of valid data of the first block;
• writing the valid data of the first block from the first memory to a second memory, wherein the first memory has a first memory type and the second memory has a second memory type different from the first memory type;
• identifying a second block of the plurality of blocks stored at the first memory based on an age of valid data of the second block;
• determining that the age of the valid data of the second block satisfies a threshold condition;
• and
• in response to determining that the age of the valid data of the second block satisfies the threshold condition, writing the valid data of the second block from the first memory to the second memory.

A system comprising:

• a first memory component having a first memory type, the first memory component comprising a plurality of blocks;
• a second memory component having a second memory type different from the first memory type;
• and
• a processing device, operatively coupled with the first memory component and the second memory component, to perform operations comprising:
• performing a garbage collection operation on first data of a first block of the plurality of blocks;
• identifying second data that remains written to a second block of the plurality of blocks after the garbage collection operation;
• determining that the second data satisfies a threshold condition;
• and
• responsive to determining that the second data satisfies the threshold condition, performing a memory flush operation on the data of the plurality of blocks.
