Abstract

Flash memory-based solid state drives (SSDs) have become ubiquitous in modern computing systems, such as high-performance servers, workstation, desktops, and laptops, due to their performance and density. The architecture of SSDs has evolved to exploit the advantages of flash memories and at the same time conceal their shortcomings. SSD concurrency techniques such as channel striping, flash-chip pipelining, die interleaving, and plane sharing utilize the available parallelism of flash memories, while the flash translation layer (FTL) operations ...
