SSD Address Field Size Reduction via Alignment-Constrained Writing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional solid state drives (SSDs) face inefficiencies in data access and organizational complexity as address fields grow, leading to performance bottlenecks and increased costs due to the need for excessive random access memory (RAM), making them economically unviable for high-capacity enterprise solutions.
Innovation Solution
The method involves using an alignment constrained writing technique that sets a logical offset equal to a physical block offset modulo, allowing data to be written efficiently in SSDs with reduced DRAM usage by constraining data locations based on logical addresses, thereby minimizing the need for excessive RAM and optimizing data storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If address fields are expanded to handle higher capacity SSDs, then storage capacity increases, but operational complexity and performance bottlenecks increase due to field padding and complex access operations
Solution Approach 1:
The patent changes the parameter of address field size by implementing a hierarchical addressing scheme that breaks down large address spaces into smaller manageable segments. Instead of using single large address fields that require padding, the system uses multiple smaller address fields (e.g., upper and lower address fields) that can be processed more efficiently without padding requirements.
2Adaptability or versatility
If higher capacity memory is incorporated to handle complex addressing, then addressing capability improves, but production cost increases prohibitively
Solution Approach 1:
The patent segments the addressing function into multiple smaller address fields rather than requiring a single large address field. This segmentation allows the system to handle high-capacity storage using standard, cost-effective memory components instead of requiring expensive high-capacity memory. The address space is divided into upper and lower fields that can be processed using conventional memory resources.
3Quantity of substance
If conventional addressing systems are used with expanded address fields, then storage capacity increases, but access efficiency decreases due to lack of bit shift operations and additional field padding
Solution Approach 1:
The patent introduces a hierarchical dimension to the addressing system by using multiple address fields (upper and lower fields) instead of a single flat address field. This dimensional change enables bit shift operations to be applied to smaller address fields individually, improving access efficiency. The hierarchical structure allows for more efficient calculation of offsets and positions without requiring padding.

AI summary
A method that uses a reduced logical and physical address field size for storing data having steps of receiving a set of data to write to a solid state drive, determining a logical address to the set of data, setting a logical offset of the set of data to be equal to a physical block offset modulo of the data and writing the set of data to the solid state drive in locations on solid state drive that accept a size of the address of the set of data is disclosed.
