Abstract
A dynamic random access memory device includes banks of dynamic memory cells. The device performs a refresh operation in response to receiving a self refresh command, by refreshing rows of the memory cells located in each of the banks. Further, a refresh frequency for the refresh operation is selected such that the refresh frequency is minimized to conserve power consumed by the memory device while being sufficient to refresh the rows of the memory cells.
