Yes, the diagnostic software is mentionning SD/MMC memory cards in various strings.
And oldest TI-Nspire ClickPad 1.x diagnostic versions even have some code to deal with them.

But of course, there is no SD/MMC reader in the TI-Nspire.
It *might*, and note I insist on the 'might', be possible to connect one through the J04/Dock connector.

Or it might just be some old code TI hasn't removed, code which was used when the TI-Nspire handhelds were still development boards.

Have a look at this early 2007 TI-Nspire ClickPad development board.
You'll be able to spot a SD/MMC reader. ;)

According to code and strings present in the oldest 1.1.xxxx diagnostic softwares, the SD/MMC reader was working and could be used to reflash the NOR chip (Boot1) and NAND chip.

The newer TI-Nspire CX diagnostic software still looks for an SD card when you trigger the "test image" test for example:
