Abstract:
A data transfer apparatus in a semiconductor memory device includes a DQ pad, a DQS pad, a DQ driver for transferring the data signal to the DQ pad according to a driver select signal, and a DQS driver for transferring data strobe signal to the DQS pad according to the driver select signal. Any one of the DQ driver and the DQS driver is activated by the driver select signal, and the driver select signal is generated by one of EMRS control code, MRS control code and test mode code.
