Memory Circuit Voltage Switching for Low-Leakage Standby
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices consume unnecessary power in standby mode due to circuit blocks receiving high operating voltages, leading to increased power consumption and leakage current.
Innovation Solution
Implementing switch sets that provide different voltage levels to circuit blocks in normal and standby modes, with higher voltages in normal mode and lower voltages in standby mode to reduce power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If circuit blocks receive high operating voltage in standby mode to maintain operation, then operational readiness is preserved, but power consumption and leakage current remain high
Solution Approach 1:
The patent applies dynamics by making the voltage supply adaptive rather than static. The switch sets dynamically adjust the voltage level provided to circuit blocks based on operational mode (normal or standby), enabling the system to transition between high voltage for full operation and low voltage for power-saving standby while maintaining operational readiness when needed.
Solution Approach 2:
The patent changes the voltage parameter from a fixed high level to a variable level that adapts to operational requirements. By providing different voltage levels (first voltage in normal mode, second voltage in standby mode) to circuit blocks, the system optimizes power consumption while preserving the ability to quickly resume full operation.
2Reliability
If circuit blocks receive high operating voltage in standby mode, then operational capability is maintained, but leakage current remains above acceptable levels
Solution Approach 1:
The switch sets enable dynamic adjustment of voltage supply, transitioning from static high voltage to adaptive voltage levels. In standby mode, the system dynamically switches to providing lower second voltage through the switch sets, reducing leakage current while maintaining sufficient operational capability for quick resume.
Solution Approach 2:
The patent changes the voltage parameter to have different values based on operational state. By providing a second voltage with a lower voltage value than the first voltage during standby mode, the system reduces leakage current while preserving operational capability, and can quickly switch back to first voltage when full operation is required.
