Modern Electronic systems solve so many difficult problems that they often seem like magic. Nonetheless, these systems all have thesame basic limitation: they need a source of electrical power! Most of the time this is a straightforward challenge for the Electronicdesigner, because there are many power-delivery solutions. Yet sometimes a device has no direct power source, and running wiresor replacing batteries is impractical. Even when long-life batteries are usable, they eventually need to be replaced, which requires aservice call.

The extraordinary growth of the World Wide Web has been fueled by the ability it gives authors to easily and cheaply distribute Electronic documents to an international audience. As Web documents have become larger and more complex, however, Web content providers have begun to experience the limitations of a medium that does not provide the extensibility, structure, and data checking needed for large-scale commercial publishing. The ability of Java applets to embed powerful data manipulation capabilities in Web clients makes even clearer the limitations of current methods for the transmittal of document data.
FLASH文件系統(tǒng)的源碼,F(xiàn)lash 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.
