Adaptive Memory Controller Depth Mapping Table Migration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional memory control systems are inadequate in managing diverse memory architectures with varying characteristics, as they lack mechanisms to utilize adaptive mechanisms effectively, leading to inefficiencies in performance, power consumption, and latency, especially with the shift towards abstracted memory and hardware where standard software interfaces are insufficient.
Innovation Solution
An adaptive memory controller that monitors statistical data from both the central processing unit and memory to dynamically manage memory configurations, including migration and reconfiguration of memory blocks, using a memory management hypervisor and memory translation unit to optimize performance and power usage based on workload and memory patterns.

Engineering Contradiction Analysis
1Adaptability or versatility
If conventional memory control systems are used, then device complexity is reduced, but memory efficiency deteriorates due to inability to manage diverse memory architectures adaptively
Solution Approach 1:
The memory control system is segmented into specialized functional units: a depth mapping table for tracking memory block locations across different memory hierarchies, a migration manager for handling data movement between memory types, and a translator for coordinating between abstracted memory interfaces and physical memory implementations. This segmentation allows each component to manage specific aspects of memory control independently, improving overall adaptability while keeping individual component complexity manageable.
Solution Approach 2:
The patent introduces an intermediary translation layer between the abstracted memory interface and the physical memory hierarchy. This translator mediates between the simplified software view of memory and the complex physical reality of multiple memory types with different characteristics, enabling conventional software to effectively manage diverse memory architectures without direct exposure to underlying complexity.
2Productivity
If memory blocks are migrated between different memory types, then memory efficiency improves through better workload matching, but retrieval latency increases during migration operations
Solution Approach 1:
The depth mapping table maintains preliminary knowledge of memory block locations and migration status before actual data retrieval occurs. By pre-tracking which blocks are in transit, which are cached, and their expected locations across different memory hierarchies, the system can prepare translation paths and coordination signals in advance, reducing latency during actual migration operations and improving overall memory management efficiency.
3Adaptability or versatility
If adaptive memory control is implemented, then cost-performance-energy trade-offs improve, but device complexity increases due to additional monitoring and management mechanisms
Solution Approach 1:
The translation unit and depth mapping table serve multiple functions simultaneously: they track memory block locations, manage migration state, coordinate between different memory types, and provide translation services for both read and write operations. This multi-functionality consolidates what would otherwise require separate specialized components, improving workload adaptability while controlling overall device complexity through shared infrastructure.

AI summary
Apparatuses and methods for adaptive control of memory are disclosed. One example apparatus includes a memory translation unit configured to receive a memory access request including a requested address and to determine a mapping state of a region of a memory associated with the requested address. The memory translation unit further configured to provide a mapped address to the memory. The mapped address is selected from one of the requested address or a translated requested address based on the state of the region of the memory associated with the requested address.
