Abstract
A memory access operation performed on a first memory unit of a memory device is detected. A counter associated with the first memory unit is modified. It is determined that the counter satisfies a threshold criterion, wherein the threshold criterion is based on a random or pseudo-random number within a margin of an average number of memory access operations. A refresh operation is performed on a second memory unit.
