    摘要: A system and method for transmitting client phase information to a host device over a bidirectional data link is described. Embodiments include detecting a phase of a clock signal relative to a data signal transmitted between a host device and a client device over a bidirectional data link. The data link includes one or more data lines each configured to transmit a corresponding bit of the data signal. The phase is encoded as client phase information and transmitted between the host and client device over the one or more data lines. The client phase information is transmitted during an electrical turnaround time period of the bidirectional data link between a read and write operation over the data link.

    摘要: A system and method for detecting errors in high-speed asymmetric interfaces are described. Embodiments include transmitting digital data between a first system component and a second system component over a bidirectional interface, wherein the first component is significantly more intelligent than the second component. The first component controls many operations of the second component, including receiving a signature from the second component over an existing line of the interface. The signature received is compared to a signature stored by the first component. Both signatures correspond to a transaction over the interface. Based on the comparison, the first component determines whether the transaction was successful, and directs the second component as necessary.

    摘要: A system and method for detecting errors in high-speed asymmetric interfaces are described. Embodiments include transmitting digital data between a first system component and a second system component over a bidirectional interface, wherein the first component is significantly more intelligent than the second component. The first component receives a signature from the second component over a line of the interface concurrent with READ and WRITE operations over the interface. The latency associated with transmission of a signature from the second component to the first component is the time taken for the second component to compute a signature. The signature received is compared to a signature stored by the first component. Both signatures correspond to a particular READ or WRITE command. Based on the comparison, the first component determines whether the READ or WRITE operation was successful, and directs the second component as necessary.

    摘要: A dynamic bus inversion (DBI) method and system are described. In various embodiments, a transmitter transmits data over a multi-bit high-speed bus to a receiver. In an embodiment, the transmitter determines whether to invert the bus based on the number of data bits that will be transitioning to a new value. If it is determined that the bus is to be inverted, the transmitter encodes a DBI signal on a shared line of the bus. In an embodiment, the shared line is used for different purposes at different times, obviating the need for a dedicated line or pin for the encoded DBI signal. The receiver receives and decodes the DBI signal and, in response, appropriately decodes the received data.

    摘要: Embodiments directed to a memory device and a memory controller that continue to operate in a low-power mode during the period required for analog timing circuitry to initialize and become usable, are described. During a low-speed to high-speed transition mode of operation for a high-speed interface, timing circuitry of the interface between the memory device and memory controller locks to a forward clock signal concurrent with the continued operation of the interface in low-speed mode. A reference clock signal configured to operate at a rate that provides both a high-speed mode and a low-speed mode and which is used as a single rate clock allows phase detection and correction circuitry to be disabled, thus allowing the idle period caused by a transition from low-speed mode to high-speed mode to be significantly reduced.
