Abstract

A method and apparatus is provided for implementing a refresh rate control scheme that is capable of compensating for external factors. Using a circuit, a change in a current leakage relating to at least a portion of a memory device is detected. Furthermore, a refresh rate associated with the portion of the memory device is adjusted in response to detecting the current leakage.
