Description: FLASH文件系统的源码，Flash memory is a nonvolatile memory, which allows the user
to electrically program (write) and erase information. The
exponential growth of flash memory has made this technology
an indispensable part of hundreds of millions of electronic
devices.
Flash memory has several significant differences with volatile
(RAM) memory and hard drive technologies which requires
unique software drivers and file systems. This paper provides
an overview of file systems for flash memory and focuses on
the unique software requirements of flash memory devices.

Description: MIPS处理器中ｆｌａｓｈ处理。功能：
Updating the contents of Flash memory without an external programmer, requires some precau-
tion when designing code that writes/erases the same Flash memory in which it is located.
Currently, no flash memories exist that allow read cycles during a write/erase cyclus. Therefore,
the code that performs the actual write/erase of the flash memory, must reside outside the flash
memory.
