Abstract
A memory device to perform a read disturb mitigation operation. For example, the memory device can measure signal and noise characteristics of a group of memory cells to determine an optimized read voltage of the group of memory cells and determine a margin of read disturb accumulated in the group of memory cells. Subsequently, the memory device can identify the group of memory cells for the read disturb mitigation operation based on the margin of read disturb and a predetermined threshold.
