Address translation in a memory sub-system for memory pooling

A computer-readable non-transitory storage medium comprising executable instructions that, when executed by a controller managing a memory device comprising a plurality of memory cells, cause the controller to:

• determine, for a plurality of logical devices, a size of a minimum allocation unit (MAU) comprising a minimum quantity of data usable by a logical device of the plurality of logical devices;
• divide the memory device into a plurality of logical units using the MAU size as a reference, wherein each logical unit has a size equal to the MAU;
• identify, using a logical device identifier (LDI) data structure, a first LDI that is available, wherein the first LDI identifies a first logical device of the plurality of logical devices;
• attempt to identify, using a logical unit identifier (LUI) data structure, a first set of LUIs that are available and consecutive, wherein the first set of LUIs identifies a first set of logical units of the plurality of logical units;
• responsive to failing to identify the consecutive set of LUIs from the first set of LUIs that are available, assign available nonconsecutive LUIs to the first set of LUIs;
• allocate the first set of logical units to the first logical device;
• and
• update an LDI-to-LUI mapping data structure to reflect that the first set of logical units are allocated to the first logical device.

A system comprising:

• a memory device;
• and
• a processing device, operatively coupled with the memory device, to perform operations comprising:
• determining, for a plurality of logical devices, a minimum allocation unit (MAU) size corresponding to a minimum quantity of data usable by a logical device of the plurality of logical devices;
• dividing the memory device into a plurality of logical units using the MAU size as a reference, wherein each logical unit has a size equal to the MAU size;
• identifying, using a logical device identifier (LDI) data structure, a first LDI that is available, wherein the first LDI identifies a first logical device of the plurality of logical devices;
• attempting to identify, using a logical unit identifier (LUI) data structure, a first set of LUIs that are available and consecutive, wherein the first set of LUIs identifies a first set of logical units of the plurality of logical units;
• responsive to failing to identify the consecutive set of LUIs from the first set of LUIs that are available, assigning available nonconsecutive LUIs to the first set of LUIs;
• allocating the first set of logical units to the first logical device;
• and
• updating an LDI-to-LUI mapping data structure to reflect allocation of the first set of logical units to the first logical device.
