Solution Overview

Problem

Current memory systems face performance issues due to access request conflicts among different memory areas, as existing memory management techniques fail to dynamically adjust address mapping to account for changing workloads, leading to memory access conflicts and delays.

Innovation Solution

Implementing a memory imbalance prediction system that identifies critical storage units with high access requests and adjusts the cache memory replacement policy to prioritize data from these units, ensuring balanced memory access by predicting and managing memory imbalances across different time intervals.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If static address mapping is used to distribute memory access requests evenly, then memory access conflicts are reduced, but the system cannot adapt to dynamic workload changes causing memory access conflicts and delays

Engineering Contradiction:
Improvememory access conflict resolutionVSAvoidadaptability to dynamic workload changes
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent applies dynamics by transitioning from static address mapping to dynamic address mapping. The system continuously monitors memory access patterns and dynamically adjusts the address mapping table to reflect changing workload characteristics. This allows the memory system to adapt to dynamic workload changes while maintaining even distribution of access requests across storage units, resolving the contradiction between static mapping reliability and dynamic adaptability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements feedback mechanisms by monitoring memory access patterns, conflict rates, and storage unit utilization in real-time. This feedback information is used to dynamically update the address mapping table, enabling the system to learn from past performance and optimize future memory access distribution. The feedback loop resolves the contradiction by allowing the system to adapt to dynamic workloads while maintaining conflict resolution effectiveness.

Inventive Principle:
Principle #23Feedback

2Adaptability or versatility

If dynamic address mapping is implemented to adapt to workload changes, then adaptability improves, but system complexity increases

Engineering Contradiction:
Improveadaptability to dynamic workload changesVSAvoidaddress mapping management complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by pre-establishing a framework for dynamic address mapping that includes monitoring mechanisms, data structures for storing access patterns, and algorithms for calculating optimal mappings. This preparation reduces the complexity of real-time decision-making by having the infrastructure already in place. The system proactively collects and processes workload information before conflicts occur, simplifying the overall management complexity while maintaining high adaptability.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements self-service by enabling the memory system to automatically monitor, analyze, and adjust its own address mapping without external intervention. The system self-optimizes by learning from its own operational data and making autonomous decisions about memory access distribution. This self-service capability reduces the complexity of centralized management while maintaining high adaptability to dynamic workloads.

Inventive Principle:
Principle #25Self-service

3Productivity

If cache memory replacement policy is adjusted based on predicted critical storage units, then memory access performance improves, but prediction and management complexity increases

Engineering Contradiction:
Improvememory access performanceVSAvoidcache management complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by predicting which storage units will be critical in future memory access patterns and proactively adjusting the cache replacement policy before conflicts occur. The system uses historical data and workload patterns to forecast future access requirements, allowing it to pre-position data in cache memory that is likely to be needed. This predictive approach improves memory access performance by ensuring critical data is already cached, while the complexity is managed through systematic prediction algorithms rather than reactive adjustments.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements local quality by applying different cache replacement strategies to different storage units based on their predicted criticality. Rather than using a uniform replacement policy for all storage units, the system identifies critical storage units with high future access probability and applies specialized cache management to them. This localized approach improves overall memory access performance by focusing cache resources on the most important data, while managing complexity through targeted rather than comprehensive management.

Inventive Principle:
Principle #3Local quality

AI summary

Embodiments of methods, apparatuses, and storage media for memory imbalance prediction-based cache memory management are disclosed herein. In one instance, the apparatus may include a memory controller associated with a memory having a plurality of storage units. The memory controller may include logic configured to determine whether the memory enters into an imbalance state based at least in part on a difference in numbers of pending access requests to different storage units, and cause an adjustment of replacement management of a cache memory, based at least in part on a result of the determination. Other embodiments may be described and/or claimed.
