1. A data storage apparatus for storing data under control by a memory controller of a separate host device, comprising:
a memory device including memory cells for storing data; and an interface circuit coupled as an interface between the host device and the memory device and configured to transmit a transmission signal to the host,
wherein the interface circuit includes a delay circuit configured to generate a delay code; and
a pre-emphasis circuit configured to generate an additional signal by delaying the transmission signal by a delay time determined based on the delay code, and to combine the transmission signal and the additional signal.
