Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional memory sub-systems face challenges in efficiently generating proof of space lookup tables during manufacturing, leading to excessive wear on solid state drives and resource wastage, as they rely on random data or predetermined patterns for burn-in, which are impractical and energy-intensive.
Innovation Solution
Pre-generation of proof of space lookup tables during the manufacturing process, allowing for pre-stored tables in memory sub-systems that can be used for proof of space activities, reducing the need for end-users to generate these tables, thereby extending the life of solid state drives and minimizing resource waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If random data or predetermined patterns are used for burn-in operations, then the manufacturing process can proceed, but excessive wear occurs on solid state drives and energy is wasted
Solution Approach 1:
The patent applies preliminary action by pre-generating proof of space lookup tables during the manufacturing burn-in process rather than generating them during end-user operation. The burn-in process creates lookup tables in advance by performing intensive read/write operations on random data, storing these tables in the memory sub-system, and then erasing the random data. This shifts the energy-intensive computation from user operation to manufacturing, resolving the contradiction between manufacturing feasibility and energy consumption.
2Ease of operation
If proof of space lookup tables are generated during end-user operation, then the memory sub-system can function, but intensive read/write operations reduce the lifespan of solid state drives
Solution Approach 1:
The patent performs the harmful read/write operations in advance during manufacturing burn-in rather than during product operation. The lookup tables are generated and stored before the product is deployed to the end user. This ensures the memory sub-system is ready for immediate proof of space operations without subjecting the solid state drive to additional wear during its operational lifespan, thus resolving the contradiction between functionality and durability.
Solution Approach 2:
The patent creates a copy of the necessary data structures (lookup tables) during manufacturing and stores them in the memory sub-system. Instead of generating these tables during operation, the system uses the pre-generated copies that were created during burn-in. This copying approach allows the system to maintain proof of space functionality while avoiding the wear that would result from generating tables during operational use.
3Duration of action of stationary object
If proof of space lookup tables are pre-generated during manufacturing, then end-users benefit from extended drive life, but the manufacturing process becomes more complex
Solution Approach 1:
The patent makes the burn-in process multi-functional by having it serve two purposes simultaneously: (1) performing the necessary wear-in operations to validate the memory sub-system, and (2) pre-generating the proof of space lookup tables. This integration of table generation into the existing burn-in workflow adds functionality without requiring a separate manufacturing step, thus resolving the contradiction between extended product lifespan and manufacturing complexity.
4Productivity
If intensive read/write operations are performed during burn-in, then lookup tables can be generated, but resource wastage occurs
Solution Approach 1:
The patent converts the harmful effect of intensive read/write operations (which would normally be considered waste during burn-in) into a beneficial outcome by using these operations to generate proof of space lookup tables. The random data written during burn-in is transformed into useful lookup tables that provide economic value in cryptocurrency networks. This transforms resource consumption from waste into productive output, resolving the contradiction between generation efficiency and resource waste.
Data Source
AI summary
A memory sub-system, such as a solid state drive (SSD), having host interface configured to receive at least read commands and write commands from an external host system. The SSD has memory cells formed on at least one integrated circuit die, and a processing device configured to control executions of the read commands to retrieve data from the memory cells and executions the write commands to store data into the memory cells. During a burn-in operation of the memory sub-system in a manufacturing facility, the memory sub-system is configured to perform read/write operations for the generation of a proof of space plot. After the burn-in operation, the memory sub-system is provided as a product of the manufacturing facility; and the proof of space plot stored in the memory sub-system is provided as a by-product of the burn-in operation.
