An output circuit of a semiconductor memory device includes a first data path, a second data path and a third data path. The first data path transfers a sense output signal, and latches the sense output signal to output the sense output signal to a first node. The second data path transfers the sense output signal, and latches the sense output signal to output the sense output signal to the first node. The third data path latches a signal of the first node, and transfers the signal of the first node to generate output data. Accordingly, the semiconductor memory device including the output circuit can operate at a relatively higher frequency using a pseudo-pipeline structured circuit, which combines a wave pipeline structure with a full pipeline structure.
