Abstract: A structure including volatile memory devices that are used by the host computer system as the storage media. The volatile memory devices include volatile memory device back up systems to provide power to both the volatile memory and non-volatile memory in the event of power failure. The volatile memory devices also connect directly to an expansion bus of the host computer system, such as a PCI bus. Therefore, the volatile memory devices of the invention include a high-speed path to the host computer system and the volatile memory devices of the invention are faster than prior art devices, use less power and are lower cost.

Abstract: A system for preventing data loss when volatile memory is used to store data either internal or external to a host computer. In the preferred embodiment, the system provides uninterrupted power to the volatile memory and to a non-volatile storage device such as a magnetic disk drive or other non-volatile memory. Upon loss of commercial power, host computer shut down, or manual initiation, the data stored in the volatile memory will be automatically backed-up to the non-volatile storage device via a high bandwidth data path. Under normal conditions, data stored in volatile memory are accessible by the host computer using a high bandwidth data path.
