    摘要： Embodiments of the invention are generally directed to systems, apparatuses, and methods for mitigating silent data corruption in a fully-buffered memory module architecture. In an embodiment, a memory controller includes a memory channel bit-lane error detector having an M-bit CRC and N-bit CRC, wherein N is less than M. The N-bit CRC is used if at least one bit-lane of the memory channel fails. In one embodiment, the memory controller selectively applies the strong error detection capability of an error correction code (ECC) in combination with the N-bit CRC to signal the need to resend faulty data, if at least one bit-channel has failed. Other embodiments are described and claimed.

    摘要： A method and apparatus of selectively flushing a conflicted write transaction from a memory controller. According to the method, a new transaction is received that identifies a memory address to which the transaction is directed. It is determined whether an address of the new transaction matches an address of any previously queued transaction. When a match occurs, the one previously queued transaction that matches the new transaction is flushed from queue.

    摘要： Method and apparatus for processing serial bus read requests in a memory controller when the memory controller interfaces to both a pipelined bus and a serial bus. According to the method, the read request message is received and is split into several atomic transactions. The atomic transactions are issued on the pipelined bus. Data related to the several atomic transactions is stored in a queue. The requested data is read from the queue and placed in a response message on the serial bus.

    摘要： A method for processing an atomic transaction in a multi-bus system that includes a local bus and a remote bus. According to the method, a first transaction in an atomic sequence is received from the local bus. The first transaction is terminated on the local bus. The first transaction is performed on the remote bus. A response to the first transaction is received and the response is placed on the local bus.

    摘要： A system for carrying two channels of data over a single physical connection. In multi-node systems, data packets are divided into flits with flits from two channels being interleaved and carried by a single physical connection. Once the flits are transmitted, they are reassembled into packets in order to be carried by a processor bus. Controllers for the channel communicate to minimize “bubbles” observed during packet assembly by the processor bus. Thus, the data is transferred in two different types of resource sharing paradigms.
