Abstract
A method for operating a data storage device may include receiving first data; generating first flagged data by adding a first flag to the first data; generating first encoded flagged data by performing an encoding operation on the first flagged data; performing a first write operation for storing the first encoded flagged data in a target position of a phase change memory region; determining whether the first write operation succeeds or falls; generating second flagged data by adding a second flag to second data obtained by inverting the first data, when it is determined that the first write operation fails; generating second encoded flagged data by performing an encoding operation on the second flagged data; and performing a second write operation for storing the second encoded flagged data in the target position.
