No - RAM is designed as a temporary storage space, and loses its contents when power is withdrawn. In most designs, this happens when the computer is switched off, but in some designs, a small amount of power continues to be drawn even when the computer is "switched off" in order to maintain the RAM content. In other special design, batteries are used to provide RAM data retention over power outages.
