Abstract
A method and apparatus are provided for controlling refresh operations of a dynamic memory device. The temperature of the dynamic memory device is detected. The detected temperature is then used to adjust a refresh rate of the dynamic memory device to compensate for increased leakage at higher temperatures and more closely tailor the timing of the refresh operations to the conditions of the dynamic memory device.
