Abstract
A data storage device includes a memory including a group of storage elements. The memory is configured to read the group of the storage elements. A controller is coupled to the memory. The controller is configured to, in response to a first error correction code (ECC) procedure determining that a first plurality of bit values obtained using a first read voltage to read the group of storage elements is uncorrectable, instruct the memory to read the group of the storage elements using a second read voltage to obtain a second plurality of bit values. The controller is further configured to compare the first plurality of bit values with the second plurality of bit values to identify a first set of bits having different values in the first plurality of bit values as compared to the second plurality of bit values and to change one or more values of the first plurality of bit values for one or more bits in the first set of bits to generate a first plurality of corrected bit values.
