Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Variations in performance capabilities among memory apparatuses from different manufacturers lead to non-uniform user experiences and unpredictable power consumption, increasing complexity in system management and the likelihood of component failure and overheating.
Innovation Solution
Implementing host configured current limits that standardize performance by setting current limits for memory operations based on capability information, allowing the host system to manage and optimize power consumption across memory apparatuses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If memory apparatuses from different manufacturers are used without standardized current limits, then manufacturing diversity and adaptability are improved, but performance uniformity and reliability deteriorate
Solution Approach 1:
The patent applies parameter changes by establishing standardized current limit parameters for different memory operation types (read, write, erase). The host system configures specific current limit values for each memory apparatus based on its capabilities, transforming the uncontrolled current consumption into a regulated parameter that ensures uniform performance across diverse manufacturers while maintaining adaptability to individual device characteristics.
Solution Approach 2:
The patent implements universality by creating a universal current limit configuration mechanism that works across memory apparatuses from different manufacturers. The host system applies a standardized approach to configure current limits for various operation types, making the system universally applicable to diverse memory devices while ensuring consistent performance standards.
2Ease of operation
If memory apparatuses operate without configured current limits, then ease of operation is improved, but power consumption predictability and thermal management deteriorate
Solution Approach 1:
The patent applies self-service by enabling the host system to automatically configure and manage current limits for memory operations. The system serves itself by establishing predictable power consumption patterns through automated current limit configuration, eliminating the need for manual intervention while ensuring reliable thermal and power management.
Solution Approach 2:
The patent implements preliminary action by configuring current limits before memory operations commence. The host system pre-establishes appropriate current limits based on memory apparatus capabilities and operation types, ensuring predictable power consumption and thermal conditions are in place before operations begin, rather than reacting to overheating or power issues after they occur.
3Productivity
If higher current limits are used to improve performance speed, then productivity is improved, but failure risk and overheating increase
Solution Approach 1:
The patent applies dynamics by implementing adaptive current limit configuration that adjusts current limits based on operation type and memory apparatus capabilities. Rather than using fixed high current limits for all operations, the system dynamically configures appropriate current limits for read, write, and erase operations, enabling high productivity when safe while preventing overheating and failure through context-appropriate current management.

AI summary
In some implementations, a memory apparatus may transmit, to a host system, capability information indicating one or more supported memory operations of the memory apparatus. The memory apparatus may receive, from the host system, configuration information indicating one or more current limits for at least one supported memory operation of the one or more supported memory operations.
