    Technically, it means you can add up to a 2 GIG SD card to expand the memory for additional programs (if you load all of the programs currently available for the HP 50G it would probably be less than 1/2 a Gig). It comes with a built in memory of 1.5 Meg or so (which is also quite a fair amount, as the typical program is measured in Kilobytes for calculators)
