Abstract
A DRAM or SDRAM component maintains an indicator that indicates whether or not an independently refreshable memory unit of a DRAM array, such as a row, contains valid data. When a refresh operation is directed to the associated memory, the refresh operation is suppressed if the memory does not contain valid data. Significant power savings may be realized by suppressing refresh operations directed to invalid data.
