Variable Trim Memory Device with Mode Register
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current memory devices require a single set of trim parameters during production, making it difficult for customers to achieve specific performance characteristics such as high throughput, long endurance, or low power consumption without requiring new production runs, leading to inefficiencies and wasted resources.
Innovation Solution
A memory device with variable trim settings and an autotuning module that allows users to select optimized trim parameters based on desired performance modes, using a mode register to choose from predefined parameter sets stored in fuse areas and automatically determining the best parameters for each usage scenario through iterative testing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a single set of trim parameters is used for production, then manufacturing simplicity is maintained, but adaptability to different usage scenarios deteriorates
Solution Approach 1:
The patent implements dynamic trim parameters that can be changed at runtime through a mode register, allowing the memory device to adapt to different usage scenarios (high throughput, long endurance, low power consumption) without requiring new production runs. This resolves the contradiction by making the parameters dynamic rather than fixed during production.
Solution Approach 2:
The patent changes the physical state or configuration of trim parameters from fixed to variable by introducing multiple parameter sets stored in fuse areas, with selection controlled by a mode register. This allows the same hardware to operate with different parameter sets depending on the desired performance characteristics.
2Adaptability or versatility
If new production runs are created for different performance requirements, then performance customization is achieved, but productivity and cost efficiency deteriorate
Solution Approach 1:
The patent makes a single production run of memory devices universal by incorporating multiple trim parameter sets within each device. The mode register allows users to select between different parameter sets (e.g., high throughput, long endurance, low power consumption) from the same hardware, eliminating the need for separate production lines for different performance levels.
3Ease of manufacture
If trim parameters are fixed after production, then manufacturing complexity is reduced, but ease of operation for optimization deteriorates
Solution Approach 1:
The patent enables end-users to self-configure the memory device for their specific needs by writing to the mode register to select appropriate trim parameter sets. This eliminates the need for manufacturers to pre-configure devices for specific applications, allowing users to optimize performance themselves based on their usage scenarios.
Data Source
AI summary
A memory device comprising a memory array comprising a plurality of memory cells, two or more fuses coupled to the memory array, wherein each of the two or more fuses contains trim data for the memory array and a mode register for selecting one of the two or more fuses to be enabled.
