Removable Memory Module for Electronic Gaming Machine Validation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic gaming machines (EGMs) face challenges in validating memory components such as BIOS and jurisdictional codes due to their embedded location, which requires removing the entire CPU for access, leading to fragile pin connectors that are easily damaged and result in excessive downtime.
Innovation Solution
A module assembly with integrally mounted memory components and an adapter switch allows for single placement in an interface device to access and validate multiple memory components, using a sturdy edge-type connector for secure attachment and reducing the risk of damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If memory components are embedded on the baseboard for security, then system security is improved, but accessibility for validation deteriorates
Solution Approach 1:
The patent segments the memory components (BIOS module and jurisdictional code module) from the main baseboard while maintaining system security. These modules are placed in a secure location but can be individually accessed through the CPU access port without removing the entire CPU, thus resolving the contradiction between security and accessibility.
2Ease of operation
If removable modules are used for validation, then accessibility is improved, but connector reliability deteriorates
Solution Approach 1:
The patent creates a virtual copy of the memory access interface through the adapter assembly. The adapter provides alternative access paths to the memory components through the CPU access port, eliminating the need for fragile physical removal of modules from hard-to-reach locations, thus improving connector reliability while maintaining accessibility.
3Ease of operation
If entire CPU is removed for memory validation, then complete access is achieved, but system downtime increases
Solution Approach 1:
The patent extracts only the necessary access capability through the adapter assembly that interfaces with the CPU access port. This allows validation of memory components without extracting (removing) the entire CPU, thus achieving complete access to memory components while minimizing system downtime.
4Measurement precision
If multiple memory components are validated separately, then thorough validation is achieved, but validation time increases
Solution Approach 1:
The adapter assembly provides a universal interface that can access multiple different memory components (BIOS module, jurisdictional code module, and other memory devices) through a single access port. This multi-functional capability allows thorough validation of all memory components while improving validation efficiency by eliminating the need for multiple separate access operations.

AI summary
An electronic gaming machine has memory components configured for easy removal during programming or validation procedures. A module may carry first and second memory devices on a module board having a module connector configured to removably attach to a baseboard carrying a processor. Accordingly, multiple memory devices may be removed and reinstalled together as a unit. An adapter may be provided to allow connection of the module to an interface device having a standard interface connector. The module may also provide status information regarding the execution of code stored on one or more of the memory devices.
