ABSTRACT:
A semiconductor memory device includes: a plurality of ports configured to perform a serial input/output (I/O) data communication with external devices; a plurality of banks configured to perform a parallel I/O data communication with the ports; a global data bus configured to transmit a signal between the banks and the ports; a test mode determiner configured to determine an operation mode of the semiconductor memory device by generating a test mode enable signal in response to a test mode control signal; a test I/O controller configured to transmit and receive a test signal with the ports in response to the test mode enable signal during a port test mode; and a plurality of selectors, each of which is configured to receive the test signal output from the corresponding port in series and feedback the test signal to the corresponding port.
