hi there! is this something you're looking for? wikihow.com/ Use-Pen-Drive-As-RAM (i'd like to help but I'm unable to post links due to forum rules. so they're are above in such way) I also heard that a usb flash can be used as and additional memory, but had no time to test it hope you'll succeed)
oh, sure. I've lost the word "video" in the initial thread topic It's possible with Ram memory, but impossible with video. You'd better buy an additional memory card if you want to increase your video memory.
