Book excerpt: Recently, flash-based Solid State Drives (SSD's) have emerged as a faster and more efficient alternative to hard drives. However, their higher cost is still an obstacle for their widespread use. Manufacturers have significantly reduced the cost by aggressively scaling the technology but this reduction has come at a price in lifetime, speed, and reliability. As the cell size shrinks and more bits are programmed into each one of them, interaction between neighboring cells increases significantly leading to noisier writing and unreliable reading of the flash memory. It is thus a signal processing challenge to write and read back reliably. This thesis proposes methods to overcome this challenge.
