Solution Overview
Problem
The performance improvement of memory systems leads to increased power consumption and heat generation, necessitating adaptive control of performance and power consumption to optimize operation in various environments.
Innovation Solution
A memory system that dynamically determines the optimum number of active memory dies associated with a zone based on configuration information, using a memory controller to manage zones and allocate a write buffer, thereby optimizing power consumption while maintaining required performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the memory system simultaneously accesses a plurality of storage areas to improve performance, then the response speed and throughput are improved, but power consumption and temperature increase
Solution Approach 1:
The memory controller dynamically determines the number of active target memory areas based on configuration information of the open zone, enabling the system to adaptively adjust the number of simultaneously accessed storage areas according to actual performance requirements and environmental conditions, thereby optimizing the balance between productivity and power consumption
2Productivity
If the memory system simultaneously accesses a plurality of storage areas to improve performance, then the response speed and throughput are improved, but temperature increases due to increased power consumption
Solution Approach 1:
The system dynamically adjusts the number of active memory areas based on configuration information, allowing temperature to be controlled by reducing the number of simultaneously accessed storage areas when thermal conditions require it, thus maintaining performance within acceptable thermal limits
3Use of energy by moving object
If the memory controller determines the number of active target memory areas based on configuration information, then power consumption is optimized, but the complexity of memory management increases
Solution Approach 1:
The memory controller automatically determines the number of active target memory areas by itself based on the configuration information of the open zone, eliminating the need for external intervention or complex manual configuration, thus optimizing power consumption while keeping the control mechanism relatively simple
