Thermal Region Tags for Memory Read Performance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic memory storage devices face inefficiencies in managing frequent temperature changes, leading to increased resource overhead and read/write latency due to premature closure of blocks during cross-temperature events, especially under high amplitude and frequency temperature variations.
Innovation Solution
The method involves detecting thermal region tags and outliers by measuring temperatures at block opening and closure, assigning blocks to thermal regions based on these measurements, and dynamically managing thermal regions to avoid premature closure and optimize read parameters, thereby reducing resource overhead and improving read performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If blocks are closed prematurely during cross-temperature events, then bit error rate is reduced, but resource overhead increases and read/write latency increases
Solution Approach 1:
The system dynamically adjusts block closure behavior based on real-time temperature monitoring. Instead of fixed premature closure, the system uses thermal region tags to determine when closure is appropriate, allowing flexible adaptation to varying temperature conditions while reducing unnecessary resource consumption
Solution Approach 2:
The system changes the parameter of block closure timing based on temperature range thresholds. By monitoring temperature differences and comparing them against predefined thresholds, the system determines optimal closure timing that balances reliability with resource efficiency
2Reliability
If blocks are closed prematurely during cross-temperature events, then bit error rate is reduced, but read performance deteriorates
Solution Approach 1:
The system segments blocks into different thermal regions based on temperature conditions. By creating thermal region tags that categorize blocks according to their temperature history, the system can apply different read parameters to different segments, optimizing read performance for each thermal region while maintaining overall reliability
Solution Approach 2:
The system performs preliminary temperature measurement and thermal region assignment before read operations. By pre-determining which thermal region a block belongs to and assigning appropriate read parameters in advance, the system reduces read latency while ensuring data integrity
3Measurement precision
If temperature monitoring is performed frequently, then cross-temperature events are detected accurately, but resource consumption increases
Solution Approach 1:
The system implements feedback by continuously monitoring temperature and using this information to adjust block management decisions. Temperature measurements feed back into the decision-making process for block closure and read parameter selection, enabling accurate detection while optimizing resource usage through intelligent feedback-driven control

AI summary
A method, device, and system for improving read performance in frequently changing device temperature conditions through detecting thermal region tags and thermal region outliers in a memory device. A plurality of thermal regions may be configured for the memory device. A first temperature may be measured corresponding to opening a storage block of the memory device for programming. A second temperature may then be measured corresponding to closing the storage block for programming. A range between the first temperature and the second temperature may be determined. The range may span N≥2 of the thermal regions. Finally, the storage block may be assigned to a thermal region that includes the second temperature, on condition that N satisfies a threshold.
