Disclosed is a memory device including an error logic unit suitable for determining whether an error is present in command signals to generate a command error signal; a replica delay circuit suitable for replicating a delay value of the error logic unit and generating an input strobe signal by delaying a strobe signal of the command signals; an output strobe signal generation circuit suitable for generating an output strobe signal activated after a command error latency elapses from a time point at which the command signals are received; and a pipe circuit suitable for receiving and storing the command error signal in response to the input strobe signal and outputting the stored command error signal in response to the output strobe signal.

Memory device

A transmitter may include a pre-driver and a main driver. The pre-driver may be configured to generate a pull-up signal and a pull-down signal in response to an enabling signal and a first data. The main driver may receive an external voltage and a ground voltage. The main driver may be configured to generate a transmission data in response to the pull-up signal and the pull-down signal. The pull-up signal and the pull-down signal may be enabled to a voltage level higher than the external voltage applied to the main driver.
