Abstract
A computer-implemented method, according to one embodiment, is for wear leveling blocks of memory. The computer-implemented method includes: determining the health of blocks of memory which are configured in multi-bit-per-cell mode. The blocks configured in multi-bit-per-cell mode are in a second pool, while blocks that are configured in single-level cell (SLC) mode are in a first pool. Moreover, the computer-implemented method is performed in some approaches with a proviso that the health of a block of memory is not determined while the block is configured in SLC mode. Moreover, health values are assigned to the blocks of memory in the second pool based on the health of the respective block. Each of the health values is further correlated with a respective data temperature.
