Solid State Floppy Disk Card [SSFDC] is the old name for SmartMedia, which was
changed in 1996. SSFDC was Developed by Toshiba Corp.
Current SmartMedia storage format include 16-Mbit, 32-Mbit, and 64-Mbit NAND-type flash
memory chips. The SmartMedia card uses an electrical contact area as shown in the graphic below.
