Abstract:
Methods and apparatuses are provided for aligning read data in a stacked semiconductor device. An example apparatus includes a stacked semiconductor device comprising stacked first and second die. The stacked semiconductor device includes a first path having a first align (first die) and second align (second die) circuits for providing read data from the second die and a second path having a first replica align (first die) and second replica align (second die) circuits. During a timing align operation, a first control circuit sets the first align and replica align circuits to a first delay value based on a propagation delay of a clock signal through the second replica align circuit. After setting of the first delay value, a second control circuit sets the second align and replica align circuits to a second delay value based on a difference in propagation delays through the first and second replica align circuits.

Claim (Index 11):
The apparatus of  claim 7 , wherein the second control circuit is configured to increase a coarse delay value of the second delay until the propagation delay of the clock signal propagated through the second replica align circuit is greater than the propagation delay of the clock signal through the first replica align circuit and to adjust a fine delay value of the second delay until the propagation delay of the clock signal propagated through the second replica align circuit is equal to the propagation delay of the clock signal through the first replica align circuit.
