Memory Controller Throttling Recovery After Reset or Hibernation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Throttling operations in storage devices are often cancelled prematurely due to hibernation or reset operations, leading to instability and increased risk of malfunction when the device resumes normal operations at maximum speed without temperature reduction.
Innovation Solution
Implement a memory controller with a temperature acquirer, throttling counter, and manager to monitor and control throttling operations, including delaying start times, managing dummy writes, and performing safety recovery modes to prevent cancellation and stabilize the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the storage device operates at maximum clock speed to improve data throughput and processing speed, then productivity increases, but temperature rises causing instability and malfunction risk
Solution Approach 1:
The system performs preliminary actions by detecting temperature trends before critical thresholds are reached and proactively initiating throttling operations. The controller monitors temperature continuously and starts throttling before the device reaches dangerous temperature levels, preventing instability while maintaining maximum performance during safe operating conditions.
2Temperature
If throttling operation is implemented to reduce temperature, then temperature control improves, but device complexity increases due to additional control mechanisms
Solution Approach 1:
The storage device performs self-service temperature management through autonomous monitoring and self-regulation. The memory controller automatically detects temperature conditions, determines when throttling is necessary, executes the throttling operation, and recovers when safe to do so - all without external intervention. This simplifies the overall system by making the device self-sufficient in thermal management.
3Use of energy by moving object
If hibernation or reset operation is performed during throttling, then power consumption reduces, but throttling cancellation causes instability
Solution Approach 1:
The system applies preliminary anti-action by detecting when hibernation or reset operations are initiated during active throttling and preventing the cancellation of the throttling state. The controller maintains the throttling configuration even after wake-up or reset, ensuring that the device does not immediately return to high-performance mode while still hot, thereby preventing thermal instability and malfunction.
4Temperature
If throttling operation is started immediately when temperature threshold is reached, then temperature control responsiveness improves, but device complexity increases due to real-time monitoring requirements
Solution Approach 1:
The memory controller performs self-service temperature monitoring and autonomous decision-making. It continuously monitors its own temperature status, compares readings against predefined thresholds, and automatically initiates or recovers from throttling operations based on current conditions. This self-sufficient approach provides immediate temperature-responsive control without requiring complex external monitoring infrastructure.

AI summary
The present disclosure relates to an operation method of a storage device, which is for overcoming the instability of the storage device caused by throttling cancellation. An operation method of a memory controller may include: acquiring a temperature of a memory; determining, on the basis of the temperature of the memory, to start a throttling operation that reduces performance of the memory; determining whether the throttling operation is cancelled; and recovering the throttling operation, which alleviates instability of the memory caused by the throttling cancellation.
