Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If signal transfer bandwidth is set to 'n' with separate dedicated transmission lines for each channel, then channel isolation and signal integrity are improved, but device utilization efficiency deteriorates and power consumption increases
Solution Approach 1:
The patent merges transmission lines between channels by enabling channels to share common transmission lines connected to memory devices. Specifically, when a memory device is activated, multiple channels can utilize the same transmission lines for signal transfer, thereby improving device utilization efficiency and reducing power consumption while maintaining signal integrity through proper signal timing and coordination.
Solution Approach 2:
The transmission lines are designed to serve multiple functions by being shared across different channels. The same transmission line can be used by different channels depending on which memory devices are activated, making the transmission lines universal rather than dedicated to a single channel, thus improving overall system efficiency.
2Productivity
If multiple memory devices are activated simultaneously with dedicated transmission lines, then channel capacity is maximized, but power consumption increases
Solution Approach 1:
The system dynamically adjusts which memory devices are activated based on actual signal transfer needs. Instead of keeping all memory devices active simultaneously, the memory control device activates only the necessary memory devices and coordinates channel usage dynamically, thereby reducing power consumption while maintaining required channel capacity.
Solution Approach 2:
The system changes the operational parameters by allowing variable bandwidth allocation and dynamic device activation. The signal transfer bandwidth can be adjusted, and memory devices can be selectively activated or deactivated based on demand, optimizing the balance between channel capacity and power consumption.
3Productivity
If channels share transmission lines, then device utilization efficiency is improved, but signal transfer complexity increases
Solution Approach 1:
The memory control device uses feedback mechanisms to manage shared transmission lines. It monitors which memory devices are active and coordinates signal transfer accordingly, using control signals to manage the shared resources. This feedback-based coordination simplifies the complexity by automating the resource allocation decisions.
Solution Approach 2:
The memory control device acts as an intermediary that manages the complexity of shared transmission lines. It handles the coordination between multiple channels and memory devices, abstracting the complexity from the individual channels and memory devices while enabling efficient shared resource utilization.
