Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing memory storage devices face a trade-off between operational stability and efficiency due to controller limitations on memory module usage, leading to reduced performance when system resources are abundant.
Innovation Solution
A memory management method that delays the execution of commands based on calculated weight values, ensuring that the sum of resource costs does not exceed a base value, thereby balancing stability and efficiency.

1Reliability
If the controller limits the number of memory modules that are busy at a certain period to avoid overheating or power overload, then the operational stability is improved, but the working efficiency is reduced when system resources are still abundant
Solution Approach 1:
The patent implements dynamic command execution control by calculating weight values for commands based on current system state (power consumption, temperature, queue depth) and comparing against a base value threshold. This dynamic adjustment allows the system to adaptively limit memory module usage when resources are constrained while permitting higher throughput when resources are abundant, resolving the contradiction between operational stability and working efficiency
Solution Approach 2:
The system changes the parameter of command execution timing by introducing weight value calculations that consider power consumption, temperature, and queue depth. By dynamically adjusting the execution decision based on these parameters and comparing against a base value, the system can optimize between stability and efficiency depending on real-time conditions

AI summary
A memory management method, a memory storage device, and a memory control circuit unit are provided. The memory management method includes: obtaining a first weight value corresponding to a first command in a command queue, wherein the command queue is used to store at least one command to be executed; obtaining a second weight value corresponding to at least one second command being executed; and in response to a sum of the first weight value and the second weight value being greater than a base value, delaying an execution of the first command.
