Abstract
A method and apparatus for efficiently download and/or upload critical data elements between a computer's memory to/from a data save disk system, when a failure of a primary power source is detected. This is accomplished by coupling the data save disk system directly to the memory module such that the data elements in the memory module may be downloaded directly to the data save disk system without any intervention by a host computer. This configuration may have a number of advantages. First, the speed at which the data elements may be downloaded from the memory module to the data save disk system may be enhanced due to the direct coupling therebetween. Second, significant power savings may be realized because only the memory module and the data save disk system need to be powered by a secondary power source to effect the download operation. This may significantly increase the amount of time that the secondary power source may power the system thereby increasing the number of data elements that can be downloaded from the memory.
