Abstract
A data management method for a memory is provided. The memory includes memory pages. Each of the memory pages includes memory cells. A data update command corresponding to a logical address is received. The logical address maps to a physical address of a target memory page before receiving the data update command. First and second reading voltages are applied to obtain at least a first and a second target memory cell to be sanitized in the target memory page of the memory pages, a first programming voltage is applied to change the logical state of the first target memory cell to a logical state with a higher threshold voltage, and a second programming voltage is applied to change the logical state of the second target memory cell to a logical state with a higher threshold voltage. The first programming voltage is different from the second programming voltage.
