Embodiment Construction

[0043] This section will describe exemplary applications of the systems and methods according to the present invention. These examples are provided only to add context and to understand the invention. It will thus be apparent to one skilled in the art that the present invention may be practiced without some or all of these specific details. In other instances, well known process steps have not been described in detail in order to avoid unnecessarily obscuring the present invention. Other applications are possible, so the following examples should not be viewed as limiting in scope or configuration. In the detailed description that follows, reference will be made to the accompanying drawings, which form a part hereof, and in which are shown by way of illustrations specific embodiments of the invention. Although these embodiments are described in sufficient detail to enable those skilled in the art to practice the invention, it is to be understood that these examples are not l...

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] The present invention relates generally to electronic gaming machines and systems, and more particularly to system architectures and storage devices relating to or within electronic gaming machines and systems. Background technique [0002] Casinos and other forms of entertainment comprise a growing multi-billion dollar industry that has undergone a dramatic shift over the past few decades to the expanded use of gaming machines, especially those based on electronics and microprocessors . [0003] Electronic gaming machines can include various hardware and software components, generally known in the art, to provide a variety of game types and game play capabilities. A typical electronic gaming machine can include hardware devices and peripherals such as, for example, bill validators, coin acceptors, card readers, keypads, buttons, joysticks, touch screens, coin hoppers, ticket printers, player tracking units, and the like. Gaming machines can also hav...
