Problems solved by technology

The former set of gauges and storage moved with the output unit, but the latter set of gauges and storage remained on the "backplate" of destroyed or altered consoles
As noted above, utilizing multiple devices to record the same or similar items is inefficient, and the degree of inefficiency grows with the number of devices and processor types used

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.

Description

technical field [0001] 本发明一般涉及电子游戏机和系统,具体地,涉及电子游戏机和系统内部或周围的系统架构和存储装置。 Background technique [0002] 由于游戏机的广泛使用,游艺场所和其他形式的游戏构成的正在增长的数十亿美元的产业在过去几十年中经历了显著的转变,并且尤其是基于电子和微处理器的游戏机。在例如视频扑克机或投币机的典型游戏机中,首先通过玩家用信用或其他标记物投注而启动玩游戏,由此游戏机确定游戏结果,将游戏结果呈现给玩家,然后根据游戏结果,可能分发某种类型的奖励。尽管对于机械游戏机和电子游戏机,该过程一般都是正确的,但电子游戏机往往更受玩家欢迎,对游艺场所更有利,原因是多方面的,例如其增加的游戏变化、更吸引人的动态呈现等等。 [0003] 电子游戏机可以包括各种硬件和软件部件,以提供多种游戏类型和玩游戏的性能。关于这些硬件和软件部件一般在现有的技术中是公知的。典型的电子游戏机可以包括硬件装置和外围设备,例如,像票单识别器、读卡器、键盘、按钮、控制杆、触摸屏、票单打印机、玩家跟踪单元等。游戏机还可以具有各种音频和视频显示部件,例如,像扬声器、显示面板、中间玻璃和顶部玻璃、外部柜装饰图、灯光、顶盒透视画、以及任意数目的各种类型的用于显示玩游戏和其它综合信息的视频显示器,这样的视频显示器的类型包括,例如,阴极射线管(“CRT”)、液晶显示器(“LCD”)、发光二极管(“LED”)、平板显示器和等离子体显示器等等。软件部件可以包括,例如,引导和初始化程序、各种玩游戏的程序和子程序、信用和支出程序、图像和音频生成程序、各种组件模块、以及随机数发生器等等。 [0004] 此外,电子游戏机典型地包括中央处理单元(“CPU”)或者主游戏控制器(“MGC”),其控制各种程序以及硬件和软件装置的组合,例如部件和程序,这些组合鼓励玩游戏、允许玩家在游戏机上玩游戏、运行游戏本身、以及控制支出和其它奖励。除了游戏机内部的很多其他处理器之外,尤其关联MGC或CPU可以使用多种类型的内存或存储装置这些存储器是不同类型的。这类存储器或存储装置可以包括,例如各种类型的随机存取存储器(“RAM”)、例如静态RAM(“SRAM”)、动态RAM(“DRAM”)、同步DRAM(“SDRAM”)、备用电池和其他类型的非易失R...
