Abstract: A receiver with clock phase calibration. A first sampling circuit generates first digital data based on an input signal, a sampling phase of the first sampling circuit controlled by a first clock signal. A second sampling circuit generates second digital data based on the input signal, a sampling phase of the second sampling circuit controlled by a second clock signal. Circuitry within the receiver calibrates the clocks in different stages. During a first calibration stage, a phase of the second clock signal is adjusted while the first digital data is selected for generating the output data. During a second calibration stage, a phase of the first clock signal is adjusted while the first digital data is selected for the output data path.

Abstract: An integrated circuit device includes a transmitter circuit operable to transmit a timing signal over a first wire to a DRAM. The DRAM receives a first signal having a balanced number of logical zero-to-one transitions and one-to-zero transitions and samples the first signal at a rising edge of the timing signal to produce a respective sampled value. The device further includes a receiver circuit to receive the respective sampled value from the DRAM over a plurality of wires separate from the first wire. In a first mode, the transmitter circuit repeatedly transmits incrementally offset versions of the timing signal to the DRAM until sampled values received from the DRAM change from a logical zero to a logical one or vice versa; and in a second mode, it transmits write data over the plurality of wires to the DRAM according to a write timing offset generated based on the sampled values.
