Abstract
In this chapter, we review the history of flash memory technology and describe the basic flash operations of erase, write, and read as well as the difference between NOR and NAND flash memory and multilevel cells. We explore the causes and alleviation of flash memory cell wear and flash bit errors. We review embedded versus removable flash memory technology (cards) and learn how flash file systems work. We see how die stacking can be used to increase the volumetric density of flash-based devices. We learn about 3D flash and emerging solid-state technologies and what we should expect about the cost of flash memory in the next few years.
