Wear-leveling algorithm
For write-intensive applications, it is recommended to implement a wear-leveling algorithm
to monitor and spread the number of write cycles per block.
In memories that do not use a wear-leveling algorithm, not all blocks get used at the same
rate. The wear-leveling algorithm ensures that equal use is made of all the available write
cycles for each block.
There are two wear-leveling levels:
1.
2.
The second level wear-leveling is triggered when the difference between the maximum and
the minimum number of write cycles per block reaches a specific threshold.
First level wear-leveling, where new data is programmed to the free blocks that have
had the fewest write cycles
Second level wear-leveling, where long-lived data is copied to another block so that the
original block can be used for more frequently changed data.
