Patent ID: 8762629

Claim:
A method for managing data stored in a memory device, the method comprising: reading user data from a first array of memory cells of the memory device having a first density; performing a data handling operation on the read user data to generate other data, wherein the data handling operation comprises changing a value of the read user data to generate the other data; and writing the other data to a second array of memory cells of the memory device, wherein the second array of memory cells stores the other data in a second density, and wherein the second density is different than the first density; wherein the value of the user data can be recovered from reading the other data from the second array of memory cells; wherein changing the value of the read user data to generate the other data comprises adjusting the value of the read user data for program disturb effects such that after the program disturb effects have taken place, the other data written to the second array of memory cells has the value of the read user data.
