Efficient scrambling and encoding for copyback procedures in a memory subsystem
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 generates a pseudorandom sequence and combines the first encoded data with the pseudorandom sequence to produce second encoded data. In this configuration, the first encoded data is scrambled based on the starting seed while, based on combining the first encoded data with the pseudorandom sequence, the second encoded data is scrambled based on the destination seed. Thereafter, the second encoded data is stored in the second location. |
