Memory Data Separation by Validity Duration for Transfer Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing memory systems inefficiently manage data transfer operations by not differentiating data based on characteristics such as validity duration or temperature, leading to increased processing, power consumption, and wear on memory cells due to transient data.
Innovation Solution
Implement data separation configurations in memory systems that evaluate and separate data based on characteristics like validity duration and temperature, optimizing transfer operations to reduce access latency, power consumption, and write amplification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data is not separated based on validity characteristics, then device complexity is reduced, but productivity decreases due to inefficient resource allocation and increased processing times
Solution Approach 1:
The patent segments data into different groups based on validity characteristics (e.g., hot data with short validity duration, cold data with long validity duration). This segmentation allows the memory system to apply different management strategies to different data groups, improving overall productivity by optimizing resource allocation for each data type while maintaining manageable complexity through structured organization.
Solution Approach 2:
The patent changes the parameter of data organization from uniform storage to differentiated storage based on validity characteristics. By introducing validity duration as a key parameter for data classification, the system achieves better productivity through targeted resource allocation without excessive complexity increase, as the differentiation is based on a single clear criterion.
2Productivity
If data separation based on validity characteristics is implemented, then productivity improves through optimized resource allocation, but device complexity increases due to additional management mechanisms
Solution Approach 1:
The patent applies local quality by treating different data groups differently based on their validity characteristics. Hot data (short validity) receives prioritized handling and faster transfer mechanisms, while cold data (long validity) uses standard processing. This localized optimization improves overall resource allocation efficiency without requiring complete system redesign, balancing productivity gains with acceptable complexity increases.
3Productivity
If concurrent transfer of multiple data types is performed, then productivity increases through parallel processing, but device complexity increases due to coordination requirements
Solution Approach 1:
The patent segments the data transfer process into separate channels or queues based on data validity characteristics. This segmentation enables concurrent transfer of hot and cold data through different pathways, achieving parallel processing that boosts productivity while keeping coordination complexity manageable through structured separation of transfer streams.

AI summary
Methods, systems, and devices for data separation configurations for memory systems are described. A memory system may store one or more characteristics of data, which may be utilized to improve performance associated with transferring the data between blocks of memory cells. For example, a memory system may be configured to evaluate whether to separate data in one or more transfer operations based on the characteristics of the data. Some transfer configurations may include transferring data independent of characteristics of the data and some other transfer configurations may include transferring data based on characteristics of the data. In some examples, a transfer configuration may include transferring data associated with a relatively longer validity duration characteristic before transferring data associated with a relatively shorter validity duration characteristic, which may include transferring data associated with different validity duration characteristics to the same target block or to different target blocks.
