Question about PS3 being able to Save on flash drives.

I have a 1GB flash drive, and next week I will be goiing on a vacation to Atlanta,GA. I'm not bringing my PS3 over there becuase my cousin already has one over there. I am bringing my game, DBZ:Burst Limit. I was wondering could my game saves from DBZ: Burst Limit could be saved onto a regular old flash drive? If so, could I plug my flash drive into my cousin's ps3 and load the game save on his PS3 and I will be able to play with all my characters?

I guess what I'm trying to say is, Can I use my flash drive as a memory card:P

how can i get my saved game data from my ps3 onto my flashdrive?
