Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional testing devices for electronic devices, particularly memory modules with high operating rates above 400 Mhz, require expensive and difficult hardware investments to handle increased data rates, and existing multiple device testing systems are inefficient and costly due to the need for additional hardware at each connection site.
Innovation Solution
A testing device with a memory controller and interface boards incorporating advanced memory buffers (AMBs) that manage data transfer between memory modules, allowing for independent testing of memory modules regardless of their operating rate, eliminating the need for costly hardware upgrades by buffering and error correction without processor overhead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional testing devices are used to test memory modules with high operating rates above 400 Mhz, then the testing can be performed, but expensive and difficult hardware investments are required
Solution Approach 1:
The patent introduces an intermediary testing device that acts as a mediator between the memory controller and memory modules. This testing device includes a processor and interface boards with buffers that can operate independently of the memory module's operating rate, allowing high-speed memory modules to be tested without requiring expensive hardware upgrades at each connection site.
Solution Approach 2:
The testing device is designed with universal interface boards that can test multiple memory modules with different operating rates using the same hardware platform. The interface boards include buffers that can handle various data rates, making the testing system multi-functional and adaptable to different memory module specifications without requiring specialized hardware for each rate.
2Productivity
If multiple electronic devices are tested concurrently using common testing modules, then testing efficiency improves, but additional hardware is required at each connection site where high operating rate devices are connected
Solution Approach 1:
The patent merges the functionality of multiple testing sites into a single centralized testing device. Instead of requiring separate expensive hardware at each connection site, the system combines multiple interface boards with buffers into one integrated platform that can concurrently test multiple memory modules, achieving both efficiency and cost-effectiveness.
Solution Approach 2:
The interface boards with buffers serve as intermediaries between the centralized testing device and the memory modules. These intermediary components handle the data rate conversion and signal buffering, allowing the single testing device to communicate with multiple high-speed memory modules without requiring additional expensive hardware at each connection point.
3Reliability
If conventional testing devices are used for high rate memory devices, then testing is possible, but the hardware does not scale to increasing complex needs
Solution Approach 1:
The testing device incorporates dynamic buffering capabilities that can adapt to different data rates. The interface boards include buffers that can dynamically adjust their operation based on the memory module's operating rate, allowing the system to scale from lower to higher data rates without hardware changes. This dynamic adaptation enables the same testing device to handle varying levels of complexity.
Solution Approach 2:
The system utilizes parameter changes in the buffer operation to adapt to different memory module speeds. By changing the buffering parameters and data transfer rates dynamically, the testing device can scale its capability to match the increasing complexity and speed requirements of different memory modules without requiring physical hardware upgrades.
