Memory Controller Unmap Operation Time Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current memory systems face inefficiencies in managing unmap operations due to varying update sizes, leading to prolonged operation times and complexities in addressing mapping information updates.
Innovation Solution
A memory controller is designed to calculate operation times for different unmap operations based on received unmap information, selecting and performing the operation with the relatively shorter update size, utilizing an unmap controller, calculator, and control processor to output appropriate unmap commands and manage mapping information updates efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the memory controller performs unmap operations with varying update sizes, then the unmap operation can handle different mapping information update requirements, but the unmap operation time becomes prolonged and inefficient
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the unmap operation mode based on the update size parameter. When the update size exceeds a threshold, the system switches from a first unmap operation mode to a second unmap operation mode, thereby optimizing operation time based on the specific parameter conditions
Solution Approach 2:
The system implements dynamics by making the unmap operation mode changeable and adaptable. The controller dynamically selects between different unmap operation modes depending on the calculated update size, allowing the system to adapt its behavior based on real-time conditions rather than using a fixed operation mode
2Productivity
If the memory controller calculates and compares operation times for multiple unmap operations, then the most efficient operation can be selected, but the control complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the unmap operation into distinct modes (first unmap operation and second unmap operation) based on update size thresholds. This segmentation allows the system to handle different scenarios with predefined operation patterns, reducing the complexity of real-time decision-making while maintaining efficiency

AI summary
The memory controller includes an unmap controller configured to receive unmap information from a host, calculate operation times required to perform a plurality of respective unmap operations based on the unmap information, and output an unmap command for an unmap operation having a relatively short operation time among the plurality of unmap operations as a result of the calculation; a buffer memory configured to store a plurality of types of address mapping information; and a control processor configured to control the unmap controller and the buffer memory in response to a command received from the host.
