7.5SMARTMEDIA CARDS (SM, PREVIOUSLY CALLED SSFDC)

SmartMedia cards, introduced in 1996, are the thinnest form factor flash storage devices. They were originally called SSFDC, for Solid-State Floppy Disk card, as they look like a miniature floppy disk. SmartMedia cards usually incorporate a single flash chip and do not incorporate a controller. Thus, they depend on the host controller to manage all memory reads and writes. The SSFDC Forum sets the specifications for SmartMedia cards.
