Modular SSD Memory Cards with M.2 Connectors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-capacity solid state drives face significant costs when a single defective memory package is installed or fails, leading to the need for an improved design that allows for individual testing and replacement of memory cards.
Innovation Solution
A modular solid state drive design featuring a controller board with individually tested and replaceable memory cards connected via industry-standard M.2 connectors, with redundant data storage for error correction and data reconstruction capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If memory packages are soldered directly to the printed circuit board in a high-capacity SSD, then the storage capacity is increased, but the cost of defect or failure increases significantly requiring entire drive scrapping
Solution Approach 1:
The patent segments the memory storage system into separate, replaceable modules. Instead of soldering all memory packages directly to the PCB, individual memory modules can be independently removed and replaced. This segmentation allows replacement of only the defective module rather than scrapping the entire drive, thus reducing the cost of defect while maintaining high storage capacity through modular architecture.
2Device complexity
If memory packages are permanently installed on the printed circuit board, then the device complexity is reduced, but the ease of repair deteriorates as individual replacement is not possible
Solution Approach 1:
The patent introduces dynamic replaceability to the memory installation system. Memory modules are designed with connectors that allow them to be dynamically inserted and removed from the PCB without permanent soldering. This dynamic design enables easy repair by allowing individual memory module replacement while maintaining relatively simple device structure through standardized connector interfaces.
3Adaptability or versatility
If industry standard M.2 connectors are used for memory modules, then the adaptability and ease of manufacture are improved, but the conductor functions must be redefined from standard definitions
Solution Approach 1:
The patent applies universality by using industry-standard M.2 connector physical interfaces for memory modules. This allows the same connector form factor to serve multiple purposes: providing mechanical attachment, electrical connectivity, and standardized installation/removal procedures. The conductor functions are redefined to match memory module requirements rather than PCIe standards, enabling universal compatibility across different memory module implementations while maintaining adaptability.

AI summary
A solid state drive with modular memory. The solid state drive may include a modular array of memory cards installed on a controller board, each memory card being connected to the controller board utilizing a respective connector. Redundant data, e.g., parity data, may be stored in the solid state drive, making it possible for a solid state drive controller on the controller board to restore the contents of a removed memory card (e.g., a memory card that has failed) on a replacement memory card installed in its place. The connector utilized to connect each memory card to the controller board may be an industry standard, commercial off the shelf connector, e.g., an M.2 connector; the functions of the conductors in the connector may be redefined, from the industry standard definitions, for the purposes of embodiments of the present invention.
