Wear leveling based on a swapping operation between sets of physical block addresses of a non-volatile memory

A method comprising

• identifying a first set of a first plurality of physical block addresses of a non-volatile memory;
• identifying a second set of a second plurality of physical block addresses of the non-volatile memory, a last physical block address of the first set being adjacent to a first physical block address of the second set;
• in response to a request to perform a wear leveling operation for the non-volatile memory, swapping, by a processing device, first data from a first physical block address of the first set with second data from the first physical block address of the second set;
• identifying a second physical block address , the second physical block address of the first set being adjacent to the first physical block address of the first set;
• and
• swapping third data from the second physical block address of the first set with fourth data from a second physical block address of the second set, the second physical block address of the second set being adjacent to the first physical block address of the second set.

An integrated circuit comprising:

• a solid-state drive (SSD) controller, coupled with a plurality of non-volatile memory devices associated with an address space of an SSD, to:
• identify a first set of a first plurality of locations of the address space of the SSD and a second set of a second plurality of locations of the address space of the SSD, a last location of the first set being adjacent to a first location of the second set;
• receive a request to perform a wear leveling operation for the SSD;
• in response to the request, swap first data from a first location of the first set with second data from the first location of the second set;
• identify a second location of the first set, the second location of the first set being adjacent to the first location of the first set;
• and
• swap third data from the second location of the first set with fourth data from a second location of the second set, the second location of the second set being adjacent to the first location of the second set.
