    摘要: A memory device includes a plurality of pairs of complimentary bit lines and a plurality of latch circuits. Each pair of the plurality of pairs of complimentary bit lines is coupled to a column of memory cells. Each latch circuit has an input coupled to a data line and a first output and a second output to provide complementary latched values dependent upon a value of the data line. For each latch of the plurality of latches, the first output is coupled to a first bit line of a pair of the plurality such that a value of the first bit line is continuously determined by the first output during memory device operation and the second output is coupled to a second bit line of the pair such that a value of the second bit line is continuously determined by the second output during memory device operation.

    摘要: A clock recovery circuit has a boundary detection circuit (20, 21, 22, 23) detecting a boundary in an input signal in accordance with a first signal, and performs recovery of a clock by controlling the timing of the first signal in accordance with the detected boundary. The clock recovery circuit has a boundary detection timing varying circuit (42) and a variation reducing circuit (9). The boundary detection timing varying circuit (42) dynamically varies boundary detection timing in the boundary detection circuit (20, 21, 22, 23) by applying a variation to the first signal, and the variation reducing circuit (9) reduces a phase variation occurring in the recovered clock in accordance with the dynamic variation of the boundary detection timing performed by the boundary detection timing varying circuit (42).

    摘要: The present invention relates to the reducing timing uncertainties in high-performance digital circuitry and more specifically, to a timing control means and a method for minimizing timing uncertainties due to skew and jitter. A means for the compensation of timing errors in multiple channel electronic devices comprising at least one register having a plurality of channels comprises: a clock for providing a clock signal; a reference signal generator for generating reference signals for deskewing the registers; wherein for each said register a corresponding feedback loop is associated for the relative alignment of register's timing, the feedback loop comprising a means for detecting a deviation from a predetermined level of probability of reading by said register a desired symbol on a boundary of two reference channel symbols in a sequence and a set of delay means which uses the detected values of probability to generate a feedback signal. The invention is preferably implemented in a self calibrated receiver and a self calibrating transmitter. Also, the invention can be employed in a digital interface between two items or within a circuit where there is a requirement for tight timing control such as requirement for a low skew between the channels of a register.

    摘要: A dynamic latch receiver device comprises a sequence of data latch devices arranged in parallel for enabling sequential latching of data signals communicated serially on a single data line. The device includes a first pointer signal generator for generating a sequence of one or more first pointer signals, each generated first pointer signal of a sequence corresponding to a specific latch device and overlapping in time with a prior generated first pointer signal of the sequence; and, a pulse converter device associated with a latch device for receiving a corresponding first pointer signal and generating a respective second pointer signal for input to a respective latch device, each second pointer signal generated in a non-overlapping sequence for triggering a respective latching of each data signal in synchronism with serially communicated data signals.
