Abstract

A device stores a plurality of applications and a list of associations for those applications. The applications are preferably stored within a secondary memory of the device, and once launched each application is loaded into RAM. Each application is preferably associated to one or more of the other applications. Preferably, no applications are launched when the device is powered on. A user selects an application, which is then launched by the device, thereby loading the application from the secondary memory to RAM. Whenever an application is determined to be associated with a currently active state application, and that associated application has yet to be loaded from secondary memory to RAM, the associated application is pre-launched such that the associated application is loaded into RAM, but is set to an inactive state.
