Claim 10:
11. A data storage device, comprising:
a memory device; and
a controller coupled to the memory device, the controller configured to:
read a first page at a target read threshold;
determine a bit error rate (BER) of the first page at the target read threshold;
calibrate the target read threshold, wherein the calibrated target read threshold is different from the target read threshold;
read a second page at the calibrated target read threshold, wherein the second page is adjacent to the first page;
determine a BER of the second page at the calibrated read threshold; and
shift the target read threshold of the first page responsive to determining that the BER of the of the second page is equal to or greater than the BER of the first page.
