Solution Overview
Problem
Current memory systems face challenges in improving data input/output performance and operational efficiency due to limitations in addressing and storage strategies, leading to performance degradation and increased overhead in handling multiple memory dies.
Innovation Solution
A memory system that employs a controller to dynamically manage read requests through interleaving operations across multiple memory dies, using a correlation operation based on the number of requests and channel configurations, without relying on strict address limitations, thereby optimizing data distribution and reducing resource usage.

Engineering Contradiction Analysis
1Productivity
If strict address limitations are imposed on memory dies, then data access control is simplified, but data input/output throughput decreases and operational efficiency deteriorates
Solution Approach 1:
The patent implements dynamic address limitation values that are adjusted based on the number of active memory dies and channel configurations. Instead of using fixed address limitations, the system dynamically modifies the address limitation value to optimize data distribution across memory dies, thereby improving I/O throughput while maintaining manageable complexity through adaptive control.
Solution Approach 2:
The system changes the address limitation parameter based on operational conditions. The address limitation value is modified according to the number of memory dies and channel assignments, allowing the system to adapt to different configurations and maximize throughput without requiring complex static addressing schemes.
2Quantity of substance
If multiple memory dies are used to increase storage capacity, then data storage capability is improved, but operational overhead increases and performance degrades
Solution Approach 1:
The patent segments data distribution across multiple memory dies using channel assignments and dynamic address limitations. Each memory die is assigned specific channels and address ranges, allowing independent management of each die while maintaining overall system efficiency. This segmentation reduces operational overhead by enabling parallel operations without requiring complex coordination between all dies.
Solution Approach 2:
The controller implements a universal address limitation mechanism that works across different numbers of memory dies and channel configurations. The same dynamic address limitation algorithm adapts to various system configurations, providing a multi-functional solution that handles different storage capacities without requiring different management approaches, thereby reducing operational overhead.
3Productivity
If interleaving operations are implemented across memory dies, then data distribution is optimized, but control complexity and resource usage increase
Solution Approach 1:
The patent implements periodic interleaving operations where data is distributed across memory dies in a systematic periodic pattern based on channel assignments. The address limitation value is adjusted periodically according to the interleaving depth and number of dies, optimizing data distribution while using simple periodic logic that consumes minimal computational resources.
