    Abstract: A clock signal is transmitted to first and second integrated circuit (IC) components via a clock signal line, the clock signal having a first arrival time at the first IC component and a second, later arrival time at the second IC component. A write command is transmitted to the first and second IC components to be sampled by those components at respective times corresponding to transitions of the clock signal, and write data is transmitted to the first and second IC components in association with the write command. First and second strobe signals are transmitted to the first and second IC components, respectively, to time reception of the first and second write data in those components. The first and second strobe signals are selected from a plurality of phase-offset timing signals to compensate for respective timing skews between the clock signal and the first and second strobe signals.

    Abstract: An memory component includes a memory bank and a command interface to receive a read-modify-write command, having an associated read address indicating a location in the memory bank and to either access read data from the location in the memory bank indicated by the read address after an adjustable delay period transpires from a time at which the read-modify-write command was received or to overlap multiple read-modify-write commands. The memory component further includes a data interface to receive write data associated with the read-modify-write command and an error correction circuit to merge the received write data with the read data to form a merged data and write the merged data to the location in the memory bank indicated by the read address.

    Abstract: A status encoder generates a checksum that encodes a status condition together with the checksum of an associated message. A receiver determines an inverse transformation that when applied to the received status-encoded checksum recovers the parity information associated with the codeword. The status condition can then be recovered based on the selection of the inverse transformation that correctly recovers the parity information from the status-encoded checksum. Beneficially, the status condition can be encoded without requiring additional signal lines or lengthening the codeword relative to conventional error correction devices.

    Abstract: A controller includes a link interface that is to couple to a first link to communicate bi-directional data and a second link to transmit unidirectional error-detection information. An encoder is to dynamically add first error-detection information to at least a portion of write data. A transmitter, coupled to the link interface, is to transmit the write data. A delay element is coupled to an output from the encoder. A receiver, coupled to the link interface, is to receive second error-detection information corresponding to at least the portion of the write data. Error-detection logic is coupled to an output from the delay element and an output from the receiver. The error-detection logic is to determine errors in at least the portion of the write data by comparing the first error-detection information and the second error-detection information, and, if an error is detected, is to assert an error condition.

    Abstract: A memory system includes a link having at least one signal line and a controller. The controller includes at least one transmitter coupled to the link to transmit first data, and a first error protection generator coupled to the transmitter. The first error protection generator dynamically adds an error detection code to at least a portion of the first data. At least one receiver is coupled to the link to receive second data. A first error detection logic determines if the second data received by the controller contains at least one error and, if an error is detected, asserts a first error condition. The system includes a memory device having at least one memory device transmitter coupled to the link to transmit the second data. A second error protection generator coupled to the memory device transmitter dynamically adds an error detection code to at least a portion of the second data.
