Memory erasure has been shown to be possible in some experimental conditions; some of the techniques currently being investigated are: drug-induced amnesia, selective memory suppression, destruction of neurons, interruption of memory, reconsolidation, [1] and the disruption of specific molecular mechanisms.
An episode of Arrested Development called Forget-Me-Now discusses the use of drug-induced amnesia for those who have seen how magicians' tricks are performed. In the PC Game Amnesia: The Dark Descent (2010), the player character, Daniel, wakes up with amnesia in the terrifying Castle Brennenburg, and must discover the truth about his memories.
