Memory Controller Zone Segmentation for Parallel Data Flushing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current memory systems face inefficiencies in managing zones smaller than the storage capacity of memory blocks, leading to suboptimal read and write operations due to limitations in parallel access and data management.
Innovation Solution
A memory system and operating method that write data corresponding to multiple zones to a first area and then flush it to a second area when specific conditions are met, utilizing multiple memory blocks to improve performance and efficiency by parallelizing data operations across multiple blocks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data is stored in a single memory block, then storage management is simple, but read and write operations cannot be performed in parallel, reducing performance
Solution Approach 1:
The invention divides the storage space into multiple zones (first zone, second zone, third zone, etc.) within the memory block, allowing different data to be stored in different zones. This segmentation enables parallel read/write operations across multiple zones simultaneously, improving productivity while maintaining manageable complexity through structured organization
2Productivity
If zone size is made smaller than memory block capacity, then data can be distributed across multiple blocks for parallel access, but zone management becomes more complex
Solution Approach 1:
The memory block is segmented into multiple zones with sizes smaller than the total block capacity. Each zone can be independently managed and accessed, enabling parallel operations. The control circuit manages these zones through a translation layer that maps logical addresses to physical zones, handling complexity automatically
Solution Approach 2:
A translation layer is introduced between the host and the memory block, acting as an intermediary that handles the mapping between logical zone addresses and physical storage locations. This mediator manages the complexity of zone tracking and address translation, allowing simpler host-side programming while enabling sophisticated parallel storage management
3Productivity
If data is written to multiple memory blocks, then parallel read/write operations can be performed, but data management and flushing operations become more complex
Solution Approach 1:
The invention segments data into different zones within memory blocks, where each zone can be flushed independently. The control circuit manages flush operations for each zone separately, allowing parallel flushing of multiple zones while reducing the complexity compared to managing a single large data structure across multiple blocks
Solution Approach 2:
The system performs preliminary actions by pre-managing zone boundaries and translation mappings before data flushing occurs. The translation layer is pre-configured with zone information, enabling the control circuit to efficiently identify and flush specific zones without complex real-time calculations during the flushing operation
