No, only C-3PO had a memory wipe.
only c-3po received a memory wipe. He says "Wipe the protocol droid's memory". And even if R2 had, his systems would still know all of its base programing and abilities. He just wouldn't remember people or events. Its like on a computer, you can wipe all of your documents and internet history, but its still gonna know if you have a mouse/keyboard/scanner/printer attached and how to make it work.
