Interface device and signal transceiving method thereof

An interface device of a semiconductor device, the interface device comprising:

• a master device, wherein a master circuit is implemented in the master device;
• and
• a plurality of slave devices, wherein the slave devices are stacked on the master device to form a three-dimensional structure, wherein a slave circuit is implemented in each of the slave devices, and each of the slave circuits are coupled to the master circuit,
• wherein each slave circuit comprises:
• a first receiver, receiving an input data from the master circuit;
• a second receiver, receiving a first clock signal from the master circuit;
• a first clock generator, coupled to the second receiver, delaying the first clock signal according to a first delay value to generate a first delayed clock signal, and generating a plurality of first sampling signals according to the first delayed clock signal;
• a first sampler, sampling the input data according to the first sampling signals to generate a plurality of first sampling results;
• and
• a first comparator, coupled to the first sampler, and generating a first comparison result by comparing the first sampling results,
• wherein the first clock generator adjusts the first delay value according to the first comparison result,
• wherein when the first sampling results are not all the same, the first comparator causes the first clock generator to increase the first delay value according to the first comparison result, and when the first sampling results are all the same, the first comparator causes the first clock generator to decrease the first delay value according to the first comparison result.
