SmartMedia is another type of Removable NAND-type small flash memory card format. The SmartMedia device size is 45 mm x 37 mm x 0.76 mm [thick]. SmartMedia cards operate using either 3.3 volt or 5 volt. 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 does not use a connector, instead it uses a contact area as shown in the graphic below.
The graphic also defines the pinout or pin locations.
