Until last week, memory cards for digital cameras performed one task: saved images and movies. Well, camera vendors sometimes use special folders and files to store additional data meant for accces by the camera only.
But now Lexar and Panasonic are announcing new lines of cards that are designed to segment memory.
The new line of memory card from Lexar has a segregated portion of memory that cannot be erased or formatted by the camera. Its' called ActiveMemory. That allows you (or the camea) to store settings that would otherwise be lost.
And the new Smart SD from Panasonic also has two areas of memory: the second stores encrypted information for personal identification.
I can't say I can see a use for these memory cards. These announcements show that companies are trying to figure out how to go beyond larger capacities/faster speeds in the otherwise mundane memory card marketplace.
