Abstract
An apparatus may include a refresh control circuit with multiple timing circuits. The timing circuits may be used to control steal rates, e.g., the rate of refresh time slots dedicated to healing victim word lines of row hammers. The timing circuits may be controlled to allow independent adjustment of the steal rates for different victim word lines. Thus, different victim word lines may be refreshed at different rates and the different rates may be independent of one another.
