Memory architecture for block migration in zns

A method comprising:

• associating a plurality of zones of a set of memory components of a memory sub-system with a plurality of internal zone groups (IZGs), each IZG being associated with a different write cursor of a plurality of write cursors;
• programming data to a first portion of the set of memory components using the plurality of write cursors, the first portion of the set of memory components being associated with a first type of storage;
• maintaining a plurality of counters, each counter of the plurality of counters being associated with a respective IZG of the plurality of IZGs and representing a quantity of zones in the respective IZG that are ready for migration from the first type of storage to a second type of storage;
• comparing a first value of a first counter associated with a first IZG of the plurality of IZGs to a second value of a second counter associated with a second IZG of the plurality of IZGs;
• selecting, based on the comparing, the first IZG for migration ahead of the second IZG based on the first value being greater than the second value;
• and
• migrating data of zones associated with the selected first IZG from the first portion of the set of memory components to a second portion of the set of memory components associated with the second type of storage, prior to migrating data of zones associated with the second IZG.

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

• associating a plurality of zones of a set of memory components with a plurality of internal zone groups (IZGs), each IZG being associated with a different write cursor of a plurality of write cursors;
• programming data to a first portion of the set of memory components using the plurality of write cursors, the first portion of the set of memory components being associated with a first type of storage;
• maintaining a plurality of counters, each counter of the plurality of counters being associated with a respective IZG of the plurality of IZGs and representing a quantity of zones in the respective IZG that are ready for migration from the first type of storage to a second type of storage;
• comparing a first value of a first counter associated with a first IZG of the plurality of IZGs to a second value of a second counter associated with a second IZG of the plurality of IZGs;
• selecting, based on the comparing, the first IZG for migration ahead of the second IZG based on the first value being greater than the second value;
• and
• migrating data of zones associated with the selected first IZG from the first portion of the set of memory components to a second portion of the set of memory components associated with the second type of storage, prior to migrating data of zones associated with the second IZG.
