Flash memory-based SSDs are popular across a wide range of data storage markets, while
the underlying storage medium—flash memory—is becoming increasingly unreliable. As a …

The relatively high cost of write operations has become the performance bottleneck of flash
memory. Write cost refers to the time needed to program a flash page using incremental-step …

Flash memory is prevalent in modern servers and devices. Coupled with the scaling down of
flash technology, the popularity of flash memory motivates the search for methods to …

Refresh schemes have been the default approach in NAND flash memory to avoid data
losses. The critical issue of the refresh schemes is that they introduce additional costs on …

Continuous technology scaling makes NAND flash cells much denser. As a result, NAND
flash is becoming more prone to various interference errors. Due to the hardware circuit …

A read reclaim method of a storage device includes detecting, at a cycle of a random
number of read operations, the number of error bits within non-selection data stored in each …

Solid state drives (SSDs) are becoming the default storage medium with the cost dropping of
NAND flash memory. However, the cost dropping driven by the density improvement and …

SSD based cache solutions are being widely utilized to improve performance in network
storage systems. With a goal of providing a cost-effective, high performing SSD cache …

The storage capacity of NAND Flash has increased by scaling down to smaller cell size and
using multi-level storage technology, but data reliability is degraded by severer retention …

Given the needs of data-intensive web services and cloud computing applications, storage
centers play an important role in serving the demanded data access while jointly …
