Solution Overview
Problem
The inefficiency of data merging operations in memory storage devices due to the dispersed logical distribution of valid data, which reduces execution efficiency.
Innovation Solution
A memory control method that dynamically determines a reading mode based on the data dispersion degree, either using a physical or logical distribution, to optimize the data merging process by sending appropriate read command sequences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If data merging operation is performed with dispersed logical distribution of valid data, then the data can be collected from source unit, but the operation takes too much time and reduces execution efficiency
Solution Approach 1:
The patent applies dynamics by making the read mode selectable and changeable based on data distribution characteristics. The system dynamically switches between first read mode (physical distribution) and second read mode (logical distribution) depending on the data dispersion degree, allowing optimal performance adaptation to different data states without being constrained to a fixed operational mode
Solution Approach 2:
The patent changes the parameter of read mode selection based on the data dispersion degree. By evaluating whether valid data is dispersed or concentrated, the system adjusts the reading strategy accordingly - using physical distribution reading when data is dispersed and logical distribution reading when data is concentrated, thereby optimizing the data merging operation efficiency
2Productivity
If a fixed read mode is used for data merging, then the operation process is simple, but the execution efficiency is reduced when data distribution does not match the read mode
Solution Approach 1:
The patent implements feedback by evaluating the data dispersion degree of valid data in the source unit before selecting the read mode. This feedback mechanism allows the system to adapt its reading strategy based on the actual data distribution state, ensuring optimal performance while maintaining a relatively simple decision-making process through clear evaluation criteria

AI summary
A memory control method is disclosed. The method includes: determining a mode for reading first data in a first management unit as a first mode or a second mode according to a data dispersion degree of the first data; reading the first data from the first management unit according to a physical distribution of the first data if the mode for reading the first data is determined as the first mode; and reading the first data from the first management unit according to a logical distribution of the first data if the mode for reading the first data is determined as the second mode. Furthermore, a memory storage device and a memory control circuit unit are also disclosed.
