    摘要: In a transceiver system a first interface receives data from a first channel using a first clock signal and transmits data to the first channel using a second clock signal. A second interface receives data from a second channel using a third clock signal and transmits data to the second channel using a fourth clock signal. A re-timer re-times data received from the first channel using the first clock signal and retransmits the data to the second channel using the fourth clock signal.

    摘要: A transceiver comprises a first interface to receive a first signal, through a first channel, from a memory device. A transmitter transmits a second signal that represents the first signal, through a second channel, to a master device. A plurality of registers stores a plurality of values provided by the master device. The plurality of values includes a first value that specifies a transmit timing adjustment to the second signal to transmit to the master device by the transmitter.

    摘要: A nonvolatile memory device that uses pulsed control and rest periods to mitigate the formation of defect precursors. A first embodiment uses pulsed bitline control, where the coupling between a memory cell channel and a reference voltage is pulsed when it is desired to change state in the associated memory cell. Each pulse may be chosen to be less than about 20 nanoseconds, while a “rest period” between pulses can be on the order of about a hundred nanoseconds or greater. Because bitline control is used, very short rise times can be enabled, enabling generation of pulse durations of 50 nanoseconds or less. In other embodiments, these methods may also be more generally applied to other conductors (e.g., wordline or substrate well, for program or erase operations); segmented wordlines or bitlines may also be used, to minimize RC loading and enable sufficiently short rise times to make pulses robust.

    摘要: An integrated circuit device having a selectable data rate clock data recovery (CDR) circuit and a selectable data rate transmit circuit. The CDR circuit includes a receive circuit to capture a plurality of samples of an input signal during a cycle of a first clock signal. A select circuit is coupled to the receive circuit to select, according to a receive data rate select signal, one of the plurality of samples to be a first selected sample of the input signal and another of the plurality of samples to be a second selected sample of the input signal. A phase control circuit is coupled to receive the first and second selected samples of the input signal and includes circuitry to compare the selected samples to determine whether the first clock signal leads or lags a transition of the input signal. The transmit circuit includes a serializing circuit to receive a parallel set of bits and to output the set of bits in sequence to an output driver in response to a first clock signal. A select circuit selects, according to a transmit data rate select signal, data bits within an outbound data value to form the parallel set of bits received within the serializing circuit. Bits within the outbound data value are selected to achieve a first data rate when the transmit data rate select signal is in a first state, and to achieve a second data rate when the transmit data rate select signal is in a second state.
