Dynamic User-Selectable Trim Profiles in Memory Components
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional memory sub-systems have limited customization capabilities due to manufacture-configured trim registers, leading to performance and reliability issues when used in applications other than their optimized settings, and require complex and time-consuming procedures for updating, which delays system initialization.
Innovation Solution
Implementing dynamic user-selectable trim profiles that allow for initialization and updating of trim registers during boot operations or in-service, enabling customization for specific applications without the need for extensive manufacturing testing, using a packet of information to identify address locations and desired modifications stored in data-structures within the memory components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manufacture-configured trim registers are used, then the memory component is optimized for specific applications, but the customization capability is limited and requires complex procedures for updating
Solution Approach 1:
The patent implements dynamic trim profiles that can be modified at runtime through API calls, transforming the static manufacture-configured trim registers into dynamic, user-modifiable parameters. This allows the memory subsystem to adapt to different applications and workloads without requiring complex manufacturing procedures or extensive testing.
Solution Approach 2:
The patent introduces a mechanism to change trim register parameters dynamically by storing multiple trim profiles in the memory device itself. Users can select and switch between different trim profiles based on application requirements, enabling parameter changes without manufacturing intervention or complex update procedures.
2Adaptability or versatility
If protected trims are used for limited customization, then the memory component can be initialized for specific uses, but the number of available trim options is limited and cannot be updated in the field
Solution Approach 1:
The patent creates multiple copies of trim profiles stored within the memory device's own memory space. Instead of relying on a single set of manufacture-configured trim registers, the system stores multiple trim profile data structures that can be loaded and applied as needed, effectively copying and multiplying the available customization options.
Solution Approach 2:
The memory subsystem performs self-configuration by storing and managing multiple trim profiles within its own memory device. The system can load, switch, and update trim profiles without external manufacturing intervention, enabling field-updatable customization capabilities through self-service operations.
3Adaptability or versatility
If trim registers are updated through communication interface commands, then customization can be performed, but substantial delay occurs before the memory subsystem is ready for normal operation
Solution Approach 1:
The patent performs trim profile configuration in advance by storing multiple pre-configured trim profiles within the memory device during manufacturing. At runtime, the system can quickly load and apply the appropriate trim profile without requiring time-consuming communication interface commands, thereby reducing boot time delay while maintaining customization flexibility.
Solution Approach 2:
The patent merges the trim configuration data with the memory device's internal storage structure by storing trim profiles in the same memory device that will be optimized. This integration eliminates the need for separate communication interface updates and allows the trim configuration to be loaded simultaneously with other memory operations, reducing overall initialization time.
Data Source
AI summary
A memory component includes a memory configured to store an updatable trim profile that is user-modifiable. The updatable trim profile includes address information corresponding to a trim register to be modified, command information corresponding to an action to be performed, and data corresponding to the action to be performed. A processing device that is coupled to the memory component is configured to receive an instruction to modify the trim register, read contents of the updatable trim profile, and modify the trim register based on the address information, the action to be performed on the trim register, and the data.
