Storage Boot Process With Conditional Verification for Fast Startup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The frequent verification of information stored in non-volatile memory devices during bootup processes leads to unnecessary boot latency and resource consumption, despite infrequent modifications to the information.
Innovation Solution
Implementing a fast bootup process that omits verification of information, allowing for reduced latency and resource consumption, while enabling a normal bootup process for verification when necessary, based on user input or controller determination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If verification of information is performed during bootup process, then security is improved, but boot latency increases
Solution Approach 1:
The patent applies dynamics by making the verification process conditional rather than static. The controller dynamically adjusts whether to perform verification based on detected changes in information stored in non-volatile memory. When changes are detected, verification is performed to ensure security; when no changes are detected, verification is skipped to reduce boot latency. This dynamic adaptation resolves the contradiction between security and boot speed.
Solution Approach 2:
The patent changes the parameter of verification execution from a fixed state (always verify) to a variable state (verify only when necessary). By monitoring information changes and adjusting the verification parameter accordingly, the system achieves both security when needed and fast boot when information remains unchanged, effectively resolving the contradiction between security requirements and boot performance.
2Reliability
If verification of information is performed during bootup process, then security is improved, but resource consumption increases
Solution Approach 1:
The system dynamically controls resource allocation for verification based on actual needs. By detecting whether information has changed since the last boot, the controller activates or deactivates the verification process accordingly. This dynamic resource management ensures security resources are consumed only when necessary, resolving the contradiction between maintaining security and minimizing resource consumption.
Solution Approach 2:
The verification execution parameter is changed from a constant high-consumption state to a variable state that adapts to system conditions. When information changes are detected, the verification parameter is activated consuming necessary resources for security; when no changes occur, the parameter is deactivated reducing resource consumption, thus resolving the contradiction between security and resource efficiency.
3Loss of time
If fast bootup process is implemented without verification, then boot latency is reduced, but security may be compromised
Solution Approach 1:
The patent implements a dynamic boot process that adapts its verification behavior based on system state. The fast bootup mode is enabled when no information changes are detected, achieving low latency. When changes are detected, the system dynamically switches to verification mode to maintain security. This dynamic switching resolves the contradiction between fast boot and security by making the process adaptive rather than fixed.
Solution Approach 2:
The verification parameter in the boot process is changed from a fixed mandatory setting to a conditional parameter. By monitoring information integrity and adjusting the verification parameter based on detected changes, the system achieves fast boot when safe (no changes) while maintaining security when necessary (changes detected), effectively resolving the contradiction between speed and security.

AI summary
Implementations described herein relate to boot processes for memory devices. In some implementations, a controller of a storage system receives a command for enabling a fast bootup process for the storage system. The fast bootup process may exclude a measurement of information retrieved from a memory device of the storage system during the fast bootup process. The controller may enable the fast bootup process based on the command. The controller may disable a normal bootup process for the storage system based on the fast bootup process being enabled. The normal bootup process may include a measurement of information retrieved from the memory device during the normal bootup process.
