    Abstract: A buffer integrated circuit device. The device comprising an output driver formed on the substrate member, the output driver having at least a command bus and an address bus. The device has a protocol and parity checking block (“Block”). The device has a table configured in the block. The table is programmable with a plurality of timing parameters. The device has a memory state block coupled to the table and a command history table coupled to the table to process protocol information for all commands that pass through the Block. The buffer integrated circuit device utilizes the protocol checking functionality to prevent failure propagation and enables data protection even in the case of host memory controller failure or system-level failure of any signal or signals on the command, control and address bus from the host memory controller to the buffer integrated device.

    Abstract: The present systems include a memory module containing a plurality of RAM chips, typically DRAM, and a memory buffer arranged to buffer data between the DRAM and a host controller. The memory buffer includes an error detection and correction circuit arranged to ensure the integrity of the stored data words. One way in which this may be accomplished is by computing parity bits for each data word and storing them in parallel with each data word. The error detection and correction circuit can be arranged to detect and correct single errors, or multi-errors if the host controller includes its own error detection and correction circuit. Alternatively, the locations of faulty storage cells can be determined and stored in an address match table, which is then used to control multiplexers that direct data around the faulty cells, to redundant DRAM chips in one embodiment or to embedded SRAM in another.

    Abstract: The present memory system includes a memory buffer having an interface arranged to buffer data and/or command bytes being written to or read from the RAM chips residing on a DIMM by a host controller. The memory buffer further includes at least one additional interface arranged to buffer data and/or command bytes between the host controller or RAM chips and one or more external devices coupled to the at least one additional interface. For example, the memory buffer may include a SATA interface and be arranged to convey data between the host controller or RAM chips and FLASH memory devices coupled to the SATA interface. The additional interfaces may include, for example, a SATA interface, an Ethernet interface, an optical interface, and/or a radio interface.
