Non-volatile memory express (NVMe) solid-state drives (SSDs) have been widely adopted
in multi-tenant cloud computing environments or multi-programming systems. The on-board …

With the bit density improvement and the 3-D flash techniques, modern NAND flash-memory-
based solid-state disks (SSDs) dramatically increase the flash storage capacity. However, in …

Redundant Array of Independent Disks (RAID) technology has been recently introduced to
flash memory based SSDs to enhance their data reliability. Although RAID increases …

RAID-enabled SSDs commonly have unbalanced I/O workloads on their components (eg,
SSD channels), as the data/parity chunks in the same stripe may have varied access …

3-D nand flash memories are the dominant storage media in modern data centers due to
their high performance, large storage capacity, and low-power consumption. However, the …

In this paper, we evaluate thermal annealing effects on the endurance of commercial off-the-
shelf (COTS) 3D NAND flash memory beyond its end-of-life. We systematically evaluate the …

The program/erase (P/E) cycle is frequently utilized as a yardstick for indicating the wear
degree of flash memory. However, this metric exhibits a significant limitation in accuracy …

The Proactive Recovery technique for flash memory, also known as the flash's Circadian
Rhythm, has shown a remarkable increase in endurance by up to nine times and a twofold …

With the increased density and the technology scaling, flash memory is more vulnerable to
noise effects, overwhelmingly lowering the data retention time. The periodic data refresh …

Flash memories are widely preferred, yet they still suffer from low endurance. The existing
passive (resting) and accelerated passive (thermal annealing) self-healing techniques have …
