Abstract

Various embodiments of the present invention are directed to different techniques for managing the storage of accumulated information in selected non-volatile memory sources at a gaming machine. In one implementation of the present invention relates to a technique for automatically and dynamically swapping critical data and/or other game related information between the non-volatile RAM and the alternate storage (e.g., disk drive) of a gaming machine as new games are activated and/or existing games are deactivated at the gaming machine.
