Do SD Memory cards work with the psp?

So do SD memory cards (ex. camera sd cards) work for the psp, or are the SanDisk Cards the only ones for the psp?

Do SD Memory cards work with the psp?
Actually yes they do, but only if you have a special device that connects into the psp's memory slot. I have one, but I never use it. If you want I'll sell it to you.

Reply:No. As of right now only Memory Stick Pro Duo cards work with the PSP. Sony and SanDisk both make these types of cards although the SanDisk cards have a higher transfer rate of memory. The largest Memory Stick Pro Duo is an 8GB card which was last time I checked $269.99 which is more than the PSP itself.
