Lexar Media Products During the data access process, the LED turns on and off.
Research on preventing damage due to dislodgment from the slot.
14-3-4 SD Card- Many compatible products.
As of January 2003, the products (total 393 models) of 59 companies are compatible with SD Memory Card.
It features standard copyright protection technology. Adapted copyright protection technology is CPRM
(Content Protection for Recordable Media) which is being used for DVD’s.
SD Memory Card slots are compatible with MMC. SD Memory Card has the same length and width as
MMC but with increased thickness. Thickness is increased so as to stack the chips for increased capacity.
To increase speed, the number of discs were increased more than MMC and so the transfer method was
changed from serial to parallel. There is no regulation on SD memory card speed capacity, therefore there
are faster ones and slower ones on the market. Currently, Matsushita SD Card transfer speed is about
10MB/sec. It is predicted that in the latter half of 2003, improving the controller will increase the speed up
to 20MB/sec.
1) Comparison of the number of MMC and SD Memory card
discs
MMC had 7 discs. But SD now has 9 discs.
This is in order to increase speed by changing the
transfer method from serial to parallel.
