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.
