1. A device, comprising:
memory cells; and
a controller configured to:
determine, as a function of time, operating parameters indicative of a data access pattern;
predict, based on the operating parameters as a function of time, an indicator of write frequency in a region of the memory cells;
determine, based on the indicator of write frequency and based on a performance indicator of a data placement scheme for the data access pattern, an optimized operation of wear leveling for the memory cells, wherein the optimized operation comprises combining at least one wear leveling operation with at least one predicted write operation; and
perform the optimized operation of wear leveling for the memory cells.
