A superblock-based flash translation layer for nand flash memory
- In EMSOFT ’06: Proceedings of the 6th ACM & IEEE International conference on Embedded software
, 2006
"... In NAND flash-based storage systems, an intermediate software layer called a flash translation layer (FTL) is usually employed to hide the erase-before-write characteristics of NAND flash memory. This paper proposes a novel superblockbased FTL scheme, which combines a set of adjacent logical blocks ..."

ii iv vTo my parents vi vii Acknowledgements I would first and foremost extend my whole-hearted gratitude to my advisors, An-drea Arpaci-Dusseau and Remzi Arpaci-Dusseau. Andrea and Remzi are the reason that I had the opportunity for this exceptional Ph.D. journey. To this day, I still re-member the moment when they took me as their student and the joy and hope in my heart. Andrea and Remzi have showed me what systems research is like and how much fun and challenging it can be. Before this journey with them, I had always liked and believed in the beauty of mathematics and theory. My initial interest in systems research happened when I took Remzi’s Advanced Operating Systems
A Temporal Locality-Aware Page-Mapped Flash Translation Layer
, 2013
"... Abstract The poor performance of random writes has been a cause of major concern which needs to be addressed to better utilize the potential of flash in enterprise-scale environments. We examine one of the important causes of this poor performance: the design of the flash translation layer (FTL) whi ..."

) which performs the virtual-to-physical address translations and hides the erase-before-write characteristics of flash. We propose a complete paradigm shift in the design of the core FTL engine from the existing techniques with our Demand-Based Flash Translation Layer (DFTL) which selectively caches
DLOOP: A Flash Translation Layer Exploiting Plane-Level Parallelism
"... Abstract—A flash translation layer (FTL) is a software layer running in the flash controller of a NAND flash memory solid-state disk (hereafter, flash SSD). It translates logical addresses received from a file system to physical addresses in flash SSD so that the linear flash memory appears to the s ..."

Achieving Page-Mapping FTL Performance at Block-Mapping FTL Cost by Hiding Address Translation
"... Abstract--Flash Translation Layer (FTL) is one of the most important components of SSD, whose main purpose is to perform logical to physical address translation in a way that is suitable to the unique physical characteristics of the Flash memory technology. The pure page-mapping FTL scheme, arguably ..."

USENIX Association 11th USENIX Conference on File and Storage Technologies (FAST ’13) 215 Getting Real: Lessons in Transitioning Research Simulations into Hardware Systems
"... Flash-based solid-state drives have revolutionized stor-age with their high performance. Their sophisticated in-ternal mechanisms have led to a plethora of research on how to optimize applications, file systems, and internal SSD designs. Due to the closed nature of commercial de-vices though, most r ..."

Using the OpenSSD Jasmine board, we develop a prototype of FlashTier’s Solid State Cache (SSC) and of the Nameless Write SSD. While the flash-translation layer changes were straightforward, we discovered un
