    摘要: A data alignment circuit of a semiconductor memory apparatus for receiving and aligning parallel data group includes a first control unit, a second control unit, a first alignment unit and a second alignment unit. The first alignment unit generates a first control signal group in response to an address group, a clock signal, and a latency signal. The second control unit generates a second control signal group in response to the address group, the clock signal, and the latency signal. The first alignment unit aligns the parallel data group as a first serial data group in response to the first control signal group. The second alignment unit aligns the parallel data group as a second serial data group in response to the second control signal group.
