Maybe. I don't think so. At least not for SD.
Remember that SD stands for 'Secure Digital' and is DRM'd. So there has to be some smarts in it to do that.

Almost no SD support the DRM features, according to Wikipedia.
(Still doesn't change the point, though. SDs are probably designed with internal firmware)

Which is more-or-less true—almost no devices in the western market use CPRM, while in Japan every single device does (it is required as part of i-Mode, which is mandated by DoCoMo).As for firmware, the SD card interface (available for free at www.sdcard.org defines accesses in terms of 512-byte “logical” sectors, practically mandating the card to implement a flash translation layer.

Doh, of course.
I read "devices" as the SD cards themselves.
