    摘要： A digital system includes a clock line carrying a clock signal and a communication bus with a signal time of flight longer than a cycle of the clock signal. A master device is connected to the communication bus and the clock line. The master device selectively applies signals to the communication bus. A set of slave devices are connected to the communication bus and the clock line. Each slave device of the set of slave devices has an associated latency delay arising from its position on the communication bus. Each slave device includes delay circuitry to compensate for the associated latency delay such that the master device observes a uniform minimum latency for each slave device in response to applying signals to the communication bus.

    摘要： A memory system includes an interconnect structure with a high speed channel and a low speed channel. A memory device with interface circuitry is coupled to the interconnect structure. The interface circuitry includes a high power interface for coupling to the high speed channel and a low power interface for coupling to the low speed channel. The memory device is operative in a low power mode and a high power mode. A memory controller is coupled to the high speed channel and the low speed channel of the interconnect structure. The memory controller is configured to transmit control information over the low speed channel to set the power mode of the memory device. The memory device is operative in a low power mode during which high power receiver circuits are turned off. The memory device is also operative in a nap mode during which an internal clock compensation circuit is left on to preserve phase information. The memory system may include multiple memory devices coupled to a daisy chained lead of the interconnect structure. The memory controller may be configured to apply control information to the interconnect structure as an encoded device identification word. The memory devices may each include a decoder for interpreting the encoded device identification word. The memory controller may be configured to apply a memory device selection signal to the interconnect structure to selectively enable the memory devices.

    摘要： An electronic device with device timing constraints includes a set of connections coupled to an interconnect structure that carries row and column commands. A memory core stores data. A memory interface is connect to the set of connections and the memory core. The memory interface includes circuitry for generating memory core timing signals in accordance with the row commands and the column commands. The memory core timing signals have timing constraints to insure correct memory core operation. The memory interface circuitry includes individual delay components for adjusting the timing of selected timing signals of the memory core timing signals.
