Abstract: Embodiments of the disclosure are drawn to apparatuses and methods for row hammer counter resets.

In some examples, a memory device may utilize residual charges that are present on the counter cells during start-up to initialize the counter memory cells. In some other examples, a memory device may utilize threshold voltage compensation (VtC) settings at start-up to initialize the counter memory cells. In some other examples, a memory device may utilize a combination of the residual charges that are present on the counter cells and VtC settings on start-up to initialize the counter memory cells.
