    • 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.
    • 公开了具有MRAM和MROM的游戏机和系统。 用于存储引导程序和其他只读代码的MROM通过切割写入连接或不向MRAM写入引脚提供PCB插座引线,或通过使用存储器集线器来阻止写入MRAM来形成。 在主机停机时,各种组件的故事板或其他记录设备监控活动记录到MRAM,可以双向移植到记录设备和MGC。 各种组件可以各自具有专用的测井设备和MRAM。 与脑盒相关的一个MRAM取代了常规机器结构的DRAM和NVRAM,并且用于常规操作使用的双重目的,并且用于安全存储以促进状态恢复。 在存储过程中数据的优先级不再需要。 与背板相关联的另一个MRAM存储与外部壳体或终端相关联的数据。
