A method includes performing a first write operation that writes data to a first memory unit of a group of memory units in a memory device, determining a write-to-write (W2W) delay based on a time difference between the first write operation and a second write operation on a memory unit in the group of memory units, wherein the second write operation occurred prior to the first write operation, identifying a threshold time criterion that is satisfied by the W2W delay, identifying a first read voltage level associated with the threshold time criterion, and associating the first read voltage level with a second memory unit of the group of memory units. The second memory unit can be associated with a second read voltage level that satisfies a selection criterion based on a comparison of the second read voltage level to the first read voltage level.
