Memory Bank Parameter Trimming via Global and Local Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing memory systems face challenges in optimizing operating parameters across multiple memory banks, leading to performance variations and inefficiencies, as global trimming information may not adequately address the unique needs of individual subsets of memory banks.
Innovation Solution
The implementation of both global and local trimming information to adjust operating parameters, allowing for fine-tuned adjustments to subsets of memory banks, using a combination of circuitry and fuse logic to route and apply trimming information effectively.

1Productivity
If global trimming information is used to adjust operating parameters for all memory banks, then overall system performance is improved, but individual subset performance variations cannot be adequately addressed
Solution Approach 1:
The patent segments the memory system into multiple subsets (e.g., memory bank groups) and applies different trimming information to each subset. This is achieved by dividing the memory array into distinct regions that can be independently trimmed, allowing each subset to receive customized operating parameter adjustments based on its specific performance characteristics rather than applying a uniform global trim to all memory banks.
Solution Approach 2:
The patent implements local quality by providing different trimming information to different subsets of memory banks. Each subset can have its own optimized operating parameters tailored to its specific performance needs, manufacturing variations, or operational characteristics. This local customization ensures that each subset achieves optimal performance while maintaining overall system reliability.
2Device complexity
If uniform operating parameters are applied to all memory banks, then system simplicity is maintained, but performance optimization for individual subsets is limited
Solution Approach 1:
The patent segments the memory system into multiple subsets that can be independently trimmed. This segmentation is implemented through separate trim circuits or trim information storage for different memory bank groups, allowing performance optimization for each subset without requiring complete redesign of the entire memory system. The segmented approach balances complexity by focusing optimization efforts on specific subsets rather than uniformly complicating the entire system.
Solution Approach 2:
The patent applies partial action by implementing trimming for only certain critical subsets of memory banks rather than all memory banks uniformly. This selective approach allows performance optimization for subsets that benefit most from customization while avoiding the excessive complexity that would result from trimming every single memory bank individually. The system applies the necessary level of complexity only where performance gains justify the added complexity.

AI summary
Methods, systems, and devices for modifying subsets of memory bank operating parameters are described. First global trimming information may be configured to adjust a first subset of operating parameters for a set of memory banks within a memory system. Second global trimming information may be configured to adjust a second subset of operating parameters for the set of memory banks. Local trimming information may be used to adjust one of the subsets of the operating parameters for a subset of the memory banks. To adjust one of the subsets of the operating parameters, the local trimming information may be combined with one of the first or second global trimming information to yield additional local trimming information that is used to adjust a corresponding subset of the operating parameters at the subset of the memory banks.
