    Abstract: A memory device including a memory array operatively coupled to an array data bus and a deserializer circuit operatively coupled with the array data bus. The deserializer circuit includes a first ring counter including a first set of flip-flops to sequentially output a set of rising edge clock signals based on a reference clock input and a second ring counter portion including a second set of flip-flop circuits to sequentially output a set of falling edge clock signals based on the reference clock input. A rising data circuit portion of the deserializer circuit includes a set of flip-flops that each receive a rising data portion from a respective latch circuit in response to a rising edge clock signal. A falling data circuit portion of the deserializer circuit includes a set of flip-flops that each receive a falling data portion from a respective latch circuit in response to a falling edge clock signal. The third set of flip-flops outputs the set of rising data portions and the fourth set of flip-flop circuits outputs the set of falling data portions to generate a synchronized data stream to output to the array data bus in response to a common clock signal.

    Abstract: An electrical circuit device includes a signal bus comprising a plurality of parallel signal paths and a calibration circuit, operatively coupled with the signal bus. The calibration circuit can perform operations including determining a representative duty cycle for a plurality of signals transferred via the plurality of parallel signal paths, the plurality of signals comprising a plurality of duty cycles and comparing the representative duty cycle for the plurality of signals transferred via the plurality of parallel signal paths to a reference value to determine a comparison result. The calibration circuit can perform further operations including adjusting, based on the comparison result, a trim value associated with the plurality of duty cycles of the plurality of signals to compensate for distortion in the plurality of duty cycles and calibrating the plurality of duty cycles of the plurality of signals using the adjusted trim value.

    Abstract: Several embodiments of electrical circuit devices and systems with clock distortion calibration circuitry are disclosed herein. In one embodiment, an electrical circuit device includes an electrical circuit die having clock distortion calibration circuitry to calibrate a clock signal. The clock distortion calibration circuitry is configured to compare a first duty cycle of a first voltage signal of the clock signal to a second duty cycle of a second voltage signal of the clock signal. Based on the comparison, the clock distortion calibration circuitry is configured to adjust a trim value associated with at least one of the first and the second duty cycles of the first and the second voltage signals, respectively, to calibrate at least one of the first and the second duty cycles and account for duty cycle distortion encountered as the clock signal propagates through a clock tree of the electrical circuit device.

    Abstract: A memory device includes a plurality of input/output (I/O) nodes, a circuit, a latch, a memory, and control logic. The plurality of I/O nodes receive a predefined data pattern. The circuit adjusts a delay for each I/O node as the predefined data pattern is received. The latch latches the data received on each I/O node. The memory stores the latched data. The control logic compares the stored latched data to an expected data pattern and sets the delay for each I/O node based on the comparison.
