Sony: why PS Vita has 512MB of RAM

Vita's 512MB of RAM enables it to run programs in the background while gamers are playing games, Sony has said.

One of those programs is cross-game voice chat via Vita's Party system.

"Part of the reason [for including 512MB of RAM] is more RAM means easier development for game developers," Sony president of Worldwide Studios Shu Yoshida told Eurogamer at Gamescom.
