    摘要： An instantaneous phase error detector (IPED) and method includes a first gate configured to logically OR output phase error signals as data to a first latch, and a second gate configured to logically combine the output phase error signals to clock the first latch. A delay element delays to the data to the first latch where the output of the first latch provides instantaneous phase error change information. A second latch is coupled to the output phase error signals to output a lead/lag signal to indicate which of the output phase error signals is leading. A phase-locked loop employing the output of the IPED is also disclosed along with static phase measurement and jitter optimization features.

    摘要： Methods and apparatus are provided for timing recovery for an input/output bus with link redundancy. A parallel input/output interface receiver includes a plurality of data receivers, each configured to respectively receive input data from a respective one of n+m channels, where n is an integer greater than one and m is an integer greater than or equal to one. The input data is non-calibration data for the n channels and is calibration data for the m channels. The interface receiver further includes a first phase adjustor configured to provide a first clock signal to the plurality of data receivers for sampling of only the non-calibration data at any given time, and a second phase adjustor configured to provide a second clock signal to the plurality of data receivers for sampling of only the calibration data at any given time.

Each phase change memory cell is coupled to a corresponding transistor. Each transistor is coupled to the word line. Each bit line is coupled to a phase change memory cell of the device. The device further comprises a programming circuit configured to program at least one phase change memory cell to the SET state by selectively applying a two-stage waveform to the word line and the bit lines of the device. In a first stage, a first predetermined low voltage and a first predetermined high voltage are applied at the word line and the bit lines, respectively. In a second stage, a second predetermined high voltage and a predetermined voltage with decreasing amplitude are applied at the word line and the bit lines, respectively.
