Claim 0:
1. A system comprising:
a memory device comprising a set of blocks; and
a processing device coupled to the memory device, the processing device configured to perform operations comprising:
obtaining a set of threshold voltage distribution width measurements for a block in the set of blocks;
determining a threshold voltage distribution width degradation rate for the block based on the set of threshold voltage distribution width measurements for the block, the threshold voltage distribution width degradation rate for the block comprising a rate of change of threshold voltage distribution width;
determining an endurance estimate for the block based on the set of threshold voltage distribution width measurements, the determining of the endurance estimate comprising determining an estimated number of program/erase cycles during which the block is able to store data reliably based on the threshold voltage distribution width degradation rate; and
managing one or more parameters of the block based on the endurance estimate.
