Address translation metadata compression in memory devices

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

• determine a physical address corresponding to a specified logical address, wherein the physical address specifies a location, on the memory device, of a data item referenced by the specified logical address;
• produce a truncated physical address by applying a predefined mathematical transformation to the determined physical address;
• and
• store, in an address translation table, an address translation table entry mapping the specified logical address to the truncated physical address.

A system comprising:

• a memory device;
• and
• a processing device, operatively coupled to the memory device, wherein the processing device is configured to:
• receive a memory access request specifying a logical address of a data item and a memory access operation to be performed with respect to the data item;
• identify, in an address translation table, an address translation table entry referenced by the logical address;
• determine a truncated physical address specified by the address translation table entry;
• restore an original physical address from the truncated physical address, wherein the original physical address specifies a location of the data item on the memory device;
• and
• perform the memory access operation using the original physical address.
