6.4 Introduction to Drivers

6.4.1 NAND

The Solid-state memory used in embedded systems is mainly flash; this
system uses NAND Flash.
NAND Flash is used as a block device, on which the file system is arranged;
interaction between the user and NAND Flash is mainly administered by a
specific file system. In order to allow for a difference in different flash
memories, the kernel inserts an MTD subsystem between the file system
and the specific flash driver for management.
Therefore, the user accesses NAND Flash through the following process:
User -> System Cal l-> VFS -> Block Device Driver -> MTD -> NAND Flash
Driver -> NAND Flash.
