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.
|Pin #||Pin name||Signal Function|
|2||CLE||Command Latch Enable|
|3||ALE||Address Latch Enable|
|6||I/O1||I/O Data Line 1|

|9||I/O4||I/O Data Line 4|
|12||Vcc||3.3v +/- 0.3 volts|
|13||I/O5||I/O Data Line 5|
|14||I/O6||I/O Data Line 6|
|15||I/O7||I/O Data Line 7|
|16||I/O8||I/O Data Line 8|
|17||PD Vcc||Power Detect Vcc|
|18||GND (optional on 32Mbit)||Ground Level Input|
|19||RY/BY||Ready / Busy (Open Drain)|
When the card notch is on the left side the card uses 5 volts, when it's on the right side the card uses 3.3v +/- 0.3 volts. The graphic below provides a comparison of the different Removable memory Card standards. Many of the different Memory Card standards have descriptions listed on this web site. The different standards based on card size are provided. Refer to the Personal Computer Buses page for more information for different memory types, as listed here.
