Systems and methods for providing a mobile memory module in an automatic transfer switch (ATS) allow the memory module to be easily removed from a controller of the ATS. The mobile memory module is a discrete, nonvolatile memory module that stores operational settings for the ATS and can be mounted and removed via a removable fastener. When thus mounted, the mobile memory module is connected to a signal path that allows data communication with a microprocessor on the controller. The microprocessor can retrieve operational settings from the mobile memory module as needed and store updated or new operational settings on the mobile memory module as required. In some embodiments, the mobile memory module has a protective outer housing that is hardened to withstand catastrophic transfer switch failure while still retaining all operational settings stored on the module.
