A method for performing a copyback procedure is described. The method includes determining to move first encoded data from a first location in a memory die to a second location. In response to determining to move the first encoded data from the first location to the second location, a starting seed, which is associated with the first location, is combined with a destination seed, which is associated with the second location, to produce a combined seed. Based on the combined seed, the method determines a pseudorandom sequence based on the combined seed and a pseudorandom sequence table, wherein the pseudorandom sequence table maps seed values to pseudorandom sequences and the determined pseudorandom sequence maps to the combined seed in the pseudorandom sequence table. The method further combines the first encoded data with the pseudorandom sequence to produce second encoded data for storage in the second location.
