Tiny embedded devices are cost and energy-sensitive, and high-density emerging non-volatile memory (NVM) can help reduce energy consumption at a fraction of the cost. However, high-density NVM has low write endurance compared to volatile memory, so i

Many NAND flash storage systems access flash memories by generating flash commands to process input/output (I/O) requests from a host system. Because the order in which flash commands are processed affects the I/O performance, command scheduling has

As big data has evolved over the past few years, a lack of storage space and I/O bandwidth has become one of the most important challenges to overcome. To mitigate these problems, data compression schemes reduce the amount of data to be stored and tr

Physically-addressable solid-state drives (PASSDs) are secondary storage devices that provide a physical address-based interface for a host system to directly control NAND flash memory. PASSDs overcome the shortcomings such as latency variability, re

Many flash storage systems divide input/output (I/O) requests that require large amounts of data into sub-requests to exploit their internal parallelism. In this case, an I/O request can be completed only after all sub-requests have been completed. T
