Abstract

Gaming machines and systems having MRAM and MROM are disclosed. MROMs for storing boot programs and other Read Only code are formed by cutting write connections or not providing PCB socket leads to MRAM write pins, or by using memory hubs to prevent writing to MRAMs. A tale-tale board or other logging device monitoring activities at various components while primary machine power is down records to MRAM, which can be dual ported to the logging device and MGC. Various components can each have dedicated logging devices and MRAMs. One MRAM associated with the brain box replaces both DRAM and NVRAM of regular machine architectures, and is used for dual purposes of regular operational use and as safe storage to facilitate a state recovery. Prioritization of data during the storage process is rendered unnecessary. Another MRAM associated with the back plane board stores data associated with the exterior housing or terminal.
