Memory Control Circuit Dynamic Threshold Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing memory storage devices frequently switch between background and normal modes due to predetermined time parameters, leading to unnecessary system performance waste and potential increased power consumption, as these parameters may not align with user habits or device purposes.
Innovation Solution
A memory management method that detects effective information from operation events and adjusts a threshold value to determine when to enter a background mode, optimizing the balance between power saving and system performance by customizing the mode transition based on operational effectiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a predetermined time parameter is used to determine mode transitions, then the memory storage device can enter background mode to save power, but frequent switching between background mode and normal mode occurs leading to system performance waste
Solution Approach 1:
The patent applies dynamics by transitioning from a static predetermined time parameter to a dynamic threshold value that adapts based on detected operation events. The threshold value changes over time based on the type and frequency of operations detected, allowing the system to optimize the balance between power saving and system performance according to actual usage patterns rather than following a fixed schedule
Solution Approach 2:
The patent implements feedback by detecting operation events (such as read/write operations, garbage collection, wear leveling) and using this information to adjust the threshold value for mode transitions. The system continuously monitors operation types and frequencies, then modifies the threshold accordingly, creating a closed-loop control system that responds to actual device behavior and usage patterns
2Productivity
If the predetermined time parameter is extended to reduce mode switching, then system performance is maintained, but power consumption increases due to delayed background mode entry
Solution Approach 1:
The threshold value dynamically adjusts based on detected operation events, allowing the system to extend the threshold when operations suggest upcoming activity (maintaining performance) while still entering background mode when operations indicate idle periods (saving power). This dynamic adjustment resolves the contradiction by making the threshold adaptive rather than fixed
Solution Approach 2:
The patent changes the parameter from a fixed predetermined time value to a variable threshold value that can be adjusted based on operation event detection. By modifying this parameter dynamically according to detected patterns, the system optimizes both performance maintenance and power consumption reduction
3Use of energy by moving object
If the predetermined time parameter is shortened to enter background mode earlier, then power consumption is reduced, but system performance suffers due to frequent mode switching
Solution Approach 1:
The system uses feedback from detected operation events to determine whether to adjust the threshold value, allowing it to enter background mode earlier when operations indicate idle periods (reducing power consumption) while avoiding premature transitions when operations suggest upcoming activity (maintaining performance)
