摘要： Apparatuses and methods for transmitting data between a plurality of chips are described. An example apparatus includes: a first chip, wherein the first chip includes a receiver that receives a data strobe signal and further generates an internal strobe signal responsive, at least in part, to the data strobe signal, the internal strobe signal including a first edge and a second edge following the first edge; a buffer circuit coupled to a set of input terminals and captures first data at the set of input terminals responsive, at least in part, to the first edge of the internal strobe signal and further captures second data at the set of input terminals responsive, at least in part, to the second edge of the internal strobe signal; a driver coupled between the buffer circuit and a set of data terminals and configured to be activated to provide the first and second data from the buffer circuit to the set of data terminals responsive, at least in part, to a control signal; and a width expanding circuit that provides the control signal responsive, at least in part, to the internal strobe signal.

摘要： Apparatuses for monitoring a signal on a conductive via are described. An example apparatus includes: a controller, a first conductive via, a second conductive via and an evaluation circuit. The controller provides a clock signal as a first signal. The first conductive via provides a second signal responsive to the first signal. The second conductive via provides a third signal responsive to the second signal. Responsive to the third signal, the evaluation circuit provides an evaluation result signal. The evaluation result signal is indicative of a frequency of the clock signal, based on a delay of the third signal relative to the clock signal. The first conductive via, the second conductive via and the evaluation circuit may be included in an interface die. The evaluation circuit may detect whether a frequency of the first signal is below a first threshold frequency and may further provide the evaluation result signal.
