Title: Apparatus and method for high performance volatile disk drive memory access using an integrated DMA engine

Abstract: A method and apparatus for high performance volatile disk drive (VDD) memory access using an integrated direct memory access (DMA) engine. In one embodiment, the method includes the detection of a data access request to VDD memory implemented within volatile system memory. Once a data access request is detected, a VDD driver may issue a DMA data request to perform the data access request from the VDD. Accordingly, in one embodiment, the job of transferring data to/from a VDD memory implemented within an allocated portion of volatile system memory is offloaded to a DMA engine, such as, for example, an integrated DMA engine within a memory controller hub (MCH). Other embodiments are described and claimed.
