    摘要: Systems, apparatuses, and methods for memory backup in a redundant array of independent disks (RAID) system are described. The methods include detecting a failure in a main power supply that supplies power to a volatile memory that is coupled to a RAID controller, switching to a temporary power supply to supply power to the volatile memory in response to detecting the main power supply failure, and transferring data from the volatile memory to a non-volatile memory coupled to the RAID controller subsequent to switching to the temporary power supply.
