Point made. Three different Associations. Though it appears that the SDA is the largest by far of the three.
Some misconceptions to be cleared up and some conceptual ideas.
Universal Flash Standard or Universal Flash Storage (UFS) is not a flash card type standard. Universal Flash Storage (UFS) is the work of JEDEC;
“Solid State Technology Association, formerly known as Joint Electron Device Engineering Council (JEDEC) or Joint Electron Device Engineering Councils, is the semiconductor engineering standardization body of the Electronic Industries Alliance (EIA), a trade association that represents all areas of the electronics industry in the United States.” Wikipedia
Their work on Universal Flash Storage (UFS) is among others; to fix a common standard for all memory cards so they can be used in all devices without adapters and should be finalized in 2009.JEDEC Member Companies
The most used and popular Flash Memory Card standards are Compact Flash and Secure Digital, and in the end; ALL memory card standards sold by the all the largest companies are developed (and often manufactured) by SANDISK
(including Sony’s Memory Stick and SxS
standard which is compliant to the ExpressCard standard created by Sony and Sandisk
Mentioned earlier in the thread is the SD Association established in 2000
by Panasonic, SanDisk Corporation
and Toshiba Corporation. (and the scary fact that Sony isn’t a member
The Compact Flash Association was founded in 1995
, (no mention by which companies). http://www.compactflash.org/
It’s chaired by Canon and other members of the board are Lexar Media, Inc., Hagiwara Sys-Com.Co.Ltd. Hewlett Packard & SanDisk
+ CFA Executive Members are Socket Mobile, Inc., SolidGear Corporation,., RED Com. Inc. a total of about 200 member companies.
(and yes, three Sony companies are members
We also have The Express Card/PCMCIA association.http://www.expresscard.org/
The Express card is more of a container which the manufacturers can put whatever they want inside including Flash memory. The Express Card/PCMCIA association is a non-profit trade association founded in 1989
and some of the companies that developed this standard are Dell, Hewlett Packard, IBM, Intel, Lexar Media, Microsoft, SCM Microsystems and Texas Instruments.PCMCIA Members
Flash memory cards are only a “Silicon” storage container that is packaged/laminated in a plastic “box”.
There are many “flash standards” within each Flash Standard; it’s just that each standard is packaged alike to a minimum standard set by the associations. The read/write speed between similar cards can vary even if the cards have the same speed notifications.
What is needed is a Movie&Music Only Card format. (M&MOC)
The most important is an agreement on the size of the Plastic Box (formfactor) and the type of interface contact.
What Flash Standard type of card the manufactures put inside “the box” is unimportant as long as the card can fit into the card slot of any MOD machine and other download devices, and the same goes for the Reader/docking station/player/set-top box//TV/PC, and that they are able to read the content off the card.
In that way we get a healthy price competition and the need for settling on one of the flash card types is gone, and there’s no need for a quarrel among the differnt Flash standards on what flash type standard to use.
If Toshiba or Samsung want to put SD or CF inside the card, it is OK!
If Sony wants to put the same as they use inside a Memory Stick or SxS inside a M&MOC, whatever it is, they can do that!
(is what's inside of a memory stick very different from what’s inside a SD or CF card? Or is it just that Sony with different packaging can sell flash memory more expensive than the competition?)
Using the same “plastic box” or packaging of the card the manufacturers can prevent the card from being used in Cameras/Phones/Tumbdrives and undermine the price and profit of their smaller conventional cards. In that way they should be able to produce and sell a M&MOC card for a low price even if it’s the same inside as in SD and CF cards.
Something like The Express card formfactor is what is needed for a Movie&Music Only Card.
Large enough to display a Movie cover and large enough to contain whatever Flash Memory Standard the different manufacturers want to put inside.
In a way; everything needed for a Movie&Music Only Card already exists today. Nothing new is needed to be invented.
In the end it’s just that some creative people with common sense and good connections and sales skills, do the basic design and put the different existing parts together and propose this to the right parties
In the end it will be SanDisk
that will be the big earner on M&MOC, because “everybody” has to pay them for the licence/IP.
But maybe SanDisk will agree to a lower licensing fee for Flash Memory that is used in a Movie&Music Only Card.
