Or go back and read all of doni's explanatory posts on what it does and how it works?

I have studied the patent for the Norris Flash File System (now referred to as MicroOS) and posted about it in #msg-1372863. There is absolutely not one shread of a claim of any security feature in the patent whatsoever.

NFFS/MOS is simply one way to write to non-volatile memory such as flash that involves the use of cache. It was filed in 1996 when the use of flash memory was in its infancy. I believe it has been completely irrelevant for several years.

The hype about it having some kind of potential to be a "global standard" was entirely false IMO.

e.Digital itself makes no claims about any security feature such as that you claim. Why?

FOR IMMEDIATE RELEASE:


E.DIGITAL RECEIVES PATENT
FOR MicroOS™ FLASH MEMORY FILE SYSTEM

MicroOS Supports IBM's New Microdrive Technology

SAN DIEGO, September 14, 1998---E.Digital (OTC: EDIG) announced that it has received the third in a series of patents protecting its core technology. United States Pat. No. 5,787,445 covers the MicroOS™, a file system devised by the Company that improves file management in devices utilizing flash memory. In addition to flash memory compatibility, the MicroOS contains built-in support for IDE hard disks and is fully MS-DOS compatible.

"This patent protects some of our most important intellectual property," stated Fred Falk, President and CEO. "MicroOS is poised for inclusion in a number of devices, such as increasingly-popular digital voice recorders, solid state music players and digital cameras."

Mr. Falk continued, "In addition, the recent introduction of IBM's 340MB capacity 'microdrive' technology permits inexpensive development of compact music and video recorders. MicroOS has been ready for the portable digital music and video explosion for some time, but was limited by the relatively high expense and low capacities available in portable devices. We see great potential for our MicroOS to be part of a new generation of powerful video and music products based on IBM's microdrive technology."

EDIG's MicroOS stores and manipulates compressed voice, image, text, graphic or video files. The highly compacted and optimized C code delivers high performance for manipulating large amounts of digital data even in the smallest applications, and it can support an unlimited number of files, directories, and subdirectories.
