Abstract: A computer system includes a plurality of memory modules that contain semiconductor memory, such as DIMMs. The system includes a host/data controller that utilizes an XOR engine to store data and parity information in a striped fashion across on a plurality of memory cartridges each containing a plurality of memory modules to create a redundant array of industry standard DIMMs (RAID). Each memory cartridge includes an independent memory controller and a corresponding control mechanism in the host/data controller to interpret the independent transitioning of each memory cartridge between various states, including a redundant-ready and a powerdown state to facilitate “hot-plug” capabilities utilizing the removable memory cartridges. Fault information may be passed between the individual memory controllers and the host/data controller to facilitate expedient fault isolation.

Abstract: Multiple output streams of video and/or audio data are simultaneously generated from a large scale memory buffer array and sent to one or more customer devices for playback. The data is sent over networks, which use one or more protocols for data communication. Thus, for each network, a transport protocol stack is generated. The transport protocol stack is generated in hardware, thus greatly improving the throughput, and increasing the number of streams that can be generated. A wide data bus and wide address bus can be utilized because the protocol stack is generated in hardware, so that higher throughput can be achieved from the large scale memory buffer array. A plurality of protocol stack generators can have access to the same block of memory, allowing many output streams to be generated from a single copy of content in the large scale memory buffer array.
