Abstract
A data storage device can check data integrity on a wordline in memory each time the data storage device exits a low-power mode. Frequent exits from the low-power mode result in the wordline being read many times, which can result in a read disturb problem. To mitigate this problem, in one embodiment disclosed herein, a different wordline is used to check data integrity each time of a plurality of times that the data storage device exits a low-power mode. Using different wordlines for the data integrity check can reduce the likelihood of a read disturb error. Other embodiments are disclosed.
