Abstract: A first timing reference signal and a second timing reference signal are sent to a memory device. The second timing reference signal has approximately a quadrature phase relationship with respect to the first timing reference signal. A plurality of serial data patterns are received from the memory device. The transitions of the first timing reference and the second timing reference determining when transitions occur between the bits of the plurality of data patterns. Timing indicators associated with when received transitions occur between the bits of the plurality of data patterns are received from the memory device. The timing indicators are each measured using a single sampler. Based on the timing indicators, a first duty cycle adjustment for the first timing reference signal, a second duty cycle adjustment for the second timing reference signal, and a quadrature phase adjustment are determined and applied.

Abstract: A memory system supports high-performance and low-power modes. The memory system includes a memory core and a core interface. The memory core employs core supply voltages that remain the same in both modes. Supply voltages and signaling rates for the core interface may be scaled down to save power. Level shifters between the memory core and core interface level shift signals as needed to accommodate the signaling voltages used by the core interface in the different modes.

Abstract: A communication channel includes a first component having a transmitter coupled to a normal signal source, and a second component having a receiver coupled to a normal signal destination. A communication link couples the first and second components. Calibration logic provides for setting an operation value for a parameter of the communication channel, such as by executing an exhaustive calibration sequence at initialization of the link. A tracking circuit, including a monitoring function, tracks drift in the parameter by monitoring a feedback signal that has a characteristic that correlates with drift in the communication channel, and updates, or indicates the need for updating of, the operation value of the parameter in response to the monitoring function.

Abstract: Self-timed interfaces and methods are provided for interfacing different timing domains. These self-timed interfaces receive a strobe signal from a component operating under a first clock domain. A first signal path of the self-timed interface couples the strobe signal to a receiver that samples data of data line under control of the strobe signal. A second signal path of the self-timed interface couples the strobe signal to an interface circuit through a hysteresis-based element. The interface circuit, under control of an output of the hysteresis-based element along with a clock signal that originates under a second clock domain, generates an interface enable signal for use in controlling data transfers between the different clock domains.

Abstract: In a data transmission system, one or more signal supply voltages for generating the signaling voltage of a signal to be transmitted are generated in a first circuit and forwarded from the first circuit to a second circuit. The second circuit may use the forwarded signal supply voltages to generate another signal to be transmitted back from the second circuit to the first circuit, thereby obviating the need to generate signal supply voltages separately in the second circuit. The first circuit may also adjust the signal supply voltages based on the signal transmitted back from the second circuit to the first circuit. The data transmission system may employ a single-ended signaling system in which the signaling voltage is referenced to a reference voltage that is a power supply voltage such as ground, shared by the first circuit and the second circuit.
