Dynamic Power Mode Switching for Memory Boot-Up Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Battery-powered devices often face boot-up failures due to insufficient power during the initial boot-up procedure, leading to repeated attempts and a potential boot-up failure loop when the memory system lacks sufficient current.
Innovation Solution
Implementing dynamic power modes for boot-up procedures, where the memory system can initiate boot-up in either a lower-power or higher-power mode based on the available power, with the host system dynamically switching between these modes to prevent failure loops.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the memory system performs boot-up procedure in higher-power mode, then the boot-up reliability is improved, but the power consumption increases
Solution Approach 1:
The patent implements dynamic power mode switching during boot-up procedures. The memory system can transition between lower-power mode and higher-power mode based on real-time power availability and boot-up progress. This dynamic adjustment allows the system to optimize between power consumption and boot-up reliability, switching to higher-power mode only when necessary to complete critical boot-up stages.
Solution Approach 2:
The patent changes power consumption parameters during the boot-up procedure. By adjusting power mode parameters dynamically based on boot-up stage and power availability, the system can ensure sufficient power for critical operations while minimizing overall power consumption. This parameter adjustment resolves the contradiction by making power usage adaptive rather than fixed.
2Use of energy by moving object
If the memory system performs boot-up procedure in lower-power mode, then the power consumption is reduced, but the boot-up reliability deteriorates
Solution Approach 1:
The system dynamically adjusts power mode during boot-up rather than maintaining a fixed lower-power mode. When power availability increases or when critical boot-up stages require more power, the system automatically switches to higher-power mode, preventing boot-up failures while still benefiting from lower-power operation during less critical phases.
Solution Approach 2:
The patent implements preliminary power mode configuration and monitoring before critical boot-up operations. The system assesses power availability and boot-up progress in advance, preparing to switch to higher-power mode proactively when conditions indicate potential boot-up failures, rather than reacting after failures occur.
3Adaptability or versatility
If the host system dynamically switches between power modes, then the adaptability to power availability is improved, but the control complexity increases
Solution Approach 1:
The patent implements feedback mechanisms where the memory system monitors power availability, boot-up progress, and system state, then automatically adjusts power mode accordingly. This closed-loop control enables adaptive power mode switching without requiring complex external control logic, as the system self-regulates based on real-time conditions.
Solution Approach 2:
The memory system performs self-service by autonomously managing its own power mode transitions during boot-up. The system independently assesses its power needs and availability, making decisions about mode switching without requiring complex host system intervention, thereby reducing overall control complexity while maintaining high adaptability.

AI summary
Methods, systems, and devices for dynamic power modes for boot-up procedures are described. A memory system may initiate a boot-up procedure according to a predefined first power mode that is associated with a first power consumption. The memory system may then determine whether to perform the boot-up procedure according to the first power mode or a second power mode associated with a different second power consumption. In cases that the memory system receives an indication of the second power mode from the host system, the memory system may perform the boot-up procedure according to the second power mode. Additionally, in cases that the memory system does not receive an indication of the second power mode from the host system, the memory system may perform the boot-up procedure according to the first power mode.
