Engineering Contradiction Analysis
1Productivity
If reserved memory blocks are statically allocated to the second area, then the second area has guaranteed storage capacity, but the first area cannot efficiently utilize available memory resources when its valid data ratio is high
Solution Approach 1:
The patent implements dynamic allocation of reserved memory blocks by continuously monitoring valid data ratios in both first and second areas. When the valid data ratio in the first area exceeds a first threshold and the valid data ratio in the second area is below a second threshold, reserved memory blocks are reallocated from the second area to the first area. This dynamic adjustment mechanism allows the system to adapt memory distribution to actual data storage needs, resolving the contradiction between static allocation guarantees and efficient resource utilization.
2Productivity
If memory blocks are reallocated frequently based on valid data ratios, then memory utilization efficiency is improved, but system complexity and overhead increase
Solution Approach 1:
The patent employs a feedback mechanism where the controller continuously monitors valid data ratios in both first and second areas and uses this information to make reallocation decisions. The monitoring component tracks the valid data ratio, and when specific threshold conditions are met (first area ratio exceeds first threshold and second area ratio is below second threshold), the processor executes reallocation of reserved memory blocks. This feedback-based approach enables efficient memory utilization while maintaining manageable system complexity through rule-based decision making.
3Duration of action of stationary object
If reserved memory blocks are reallocated to balance valid data ratios, then operational lifespan is extended, but data processing time is increased due to additional monitoring and comparison operations
Solution Approach 1:
The patent performs preliminary monitoring of valid data ratios and evaluates threshold conditions before executing reallocation operations. By continuously tracking the valid data ratio in both areas and comparing against predetermined thresholds in advance, the system can proactively reallocate reserved memory blocks before severe imbalances occur, thereby extending memory device lifespan while minimizing the impact on data processing time through efficient threshold-based decision making.

AI summary
A memory system may include a memory device including a plurality of memory blocks; and a controller suitable for controlling the memory device. The controller may include a monitor suitable for monitoring valid data ratios of a first area and a second area and a processor suitable for comparing a first valid data ratio of the first area to a first threshold value, comparing a second valid data ratio of the second area to a second threshold value, and reallocating a target reserved memory block, which is allocated to the second area, to the first area according to the two comparison results.
