t NAND Flash memory has become the preferred nonvolatile choice for
portable consumer electronic devices. Features such as high density, low cost, and
fast write times make NAND perfectly suited for media applications where large
files of sequential data need to be loaded into the memory quickly and repeatedly.
This chapter starts with an overview of the basic functionalities of the NAND
Flash storage. Popular devices like Flash cards are then described as an example of
NAND-based systems. The last part of this chapter deals with all the state-of-the-art
technologies used to reduce the equivalent bit size. In particular, the reader will find
an overview of the multilevel storage and of the 3D solutions from single-die 3D
architectures to packages containing multiple dies.
