20 Claims

1. A system comprising:

a memory device; and

a processing device, operatively coupled with the memory device, to perform operations comprising:

identifying a first set of bits associated with a translation unit of the memory device, wherein the first set of bits corresponds to a page field;

identifying a second set of bits associated with the translation unit of the memory device, wherein the second set of bits corresponds to a block field;

updating a first portion of an address mapping table corresponding to the second set of bits with a value representing a difference between a value stored in the page field and a threshold value;

updating a second portion of the address mapping table corresponding to the first set of bits with a value representing a block number stored in the block field;

determining, based on the updated first portion and the updated second portion of the address mapping table, that a swapping condition is satisfied, wherein the swapping condition indicates that the page field and the block field are swapped; and

responsive to determining that the swapping condition is satisfied, performing a data access operation on a set of memory cells residing at a location corresponding to the translation unit.
