Abstract: A memory controller includes a transmit circuit coupled to an output node and a receive circuit coupled to an input node. The transmit circuit transmits first data to a memory device through the output node and the receive circuit is configured to receive second data from the memory device through the input node.

The first reference voltage, the second reference voltage, the driver impedance and the termination impedance are selected from a set of pre-determined values, which are associated with different signaling modes for communication of the first data and the second data.

Abstract: A signaling system employs parallel termination for a timing reference signal and series termination for information signals that may be sampled using the timing reference signal. In this way, the system may provide desired levels of signal performance and power consumption. In addition, the system may be configured such that the initial wavefronts of these signals may travel in opposite directions along complementary signaling paths. For example, a timing reference signal that travels from a driving device (e.g., a memory controller) to several destination devices (e.g., memory devices) in a multi-drop/fly-by fashion may arrive at the destination devices in a given order. In contrast, associated information signals may travel from the driving device to the destination devices such that they arrive at the destination devices in the opposite order.

Abstract: A data system component having a state machine circuit and receivers that utilize high and low threshold signals permits accurate detection of strobe signal pattern edges such as those for preamble, burst and post-amble conditions in the strobe signal. The state machine circuit may then be configured to set conditions associated with further circuit elements such as for power saving, data reception, on-die termination, etc. based on the conditions detected in the strobe signal to improve data or memory system performance. The components may be implemented as part of memory controllers and/or memory such as a dynamic random access memory and used in memory read and write operations.

Abstract: An integrated circuit device includes a delay circuit, sampling circuit and delay control circuit that cooperate to carry out adaptive timing calibration. The delay circuit generates a timing signal by delaying an aperiodic input signal for a first interval. The sampling circuit samples a data signal in response to the timing signal to generate a sequence of data samples, and also samples the data signal in response to a phase-shifted version of the timing signal to generate a sequence of edge samples. The delay control circuit adjusts the first interval based, at least in part, on a phase error indicated by the sequence of data samples and the sequence of edge samples.
