description A method, system, and apparatus for maintaining the contents of a self-refreshable memory device during periods of data processing system reset is provided. In one embodiment, a refresh controller receives an indication that the data processing system is being reset. If necessary, the refresh controller modifies the signal from a memory controller to the memory device such that the memory device is placed in a self-refresh mode. The refresh controller keeps the memory device in the self-refresh mode until the data processing system re-enables external refresh signals.
