NVMdurance Adaptive Flash Tuning patent granted
NVMdurance, with its unique approach to extending the endurance of flash devices and enabling 3D NAND, has announced that patent number 9,569,120 developed by Joe Sullivan and Conor Ryan, both of Limerick, Ireland, has been granted in the USA for Adaptive Flash Tuning.
This is the fifth patent granted by NVMdurance, founded in 2013. The first was granted in the USA in 2015. Two others have been granted in USA (US Pat No 8,984,210 and US Pat No 9,262.319), one in China (ZL 20`0 8 0052625.2; NVMD-002CN), and one in Ireland (S85799).
This patent covers NVMdurance Pathfinder and Navigator software, which discover optimal flash trim sets for the target application and implement a set of optimization techniques that constantly monitor the NAND flash health and autonomically adjusts the operating parameters in real time.
Before the flash memory product goes into production, NVMdurance Pathfinder determines multiple sets of viable flash register values, using a custom-built suite of machine-learning techniques. Then, running on the flash memory controller utilized in SSDs or other storage product, NVMdurance Navigator chooses which of these predetermined sets to use for each stage of life to increase the flash memory endurance.
NVMdurance software ensures that the flash lasts as long as possible without disclosure of “test” mode” information from the flash manufacturer. In an offline characterization phase, ‘test chips’ from a batch of recently manufactured flash memory chips are used to simulate various usage scenarios and measure the performance effects of writing and attempting to read test patterns written with different sets of operating parameters over time, simulating desired retention periods.
“The granting of this Adaptive Flash Tuning patent further proves how NVMdurance extends endurance and provides the ability to optimize NAND flash memory for the intended application,” said Pearse Coyle, NVMdurance CEO. “We will continue to file patent claims around the world to protect our unique solution.”
Congrats Pearse Coyle Kevin Kilbuck and the rest of the nvmdurance team! Keep up the good work!
Zsolt's writing a longer than expected novel
7 年The 3 things which make NVMdurance's technology processes a viable business model for SSD partners is that the heavyweight processing is done back at HQ as part of the memory characterization and controller modeling which means that the delivery overhead in each shipped product is lightweight and protects the stakeholder's IP. And the 3rd thing is that no one has come up with any better ideas for a way to roll out a new SSD with new flash memory encapsulated in such a predictable set of algorithmically bounded phases which reduces the worst risks (of delay and miss-fire) which come from the organic talent alternatives.
