ABSTRACT:
A semiconductor memory device is disclosed. The device comprises at least one data input/output reference signal input and output pin and a plurality of integrated circuits, each with a data input/output reference signal input and output pad connected to the data input/output reference signal input and output pin. Each integrated circuit further comprises a data input/output reference signal input and output buffer for buffering a data input/output reference signal input from the data input/output reference signal input and output pad when data is input. This buffer also buffers an internally generated data input/output reference signal, and outputs the buffered signal when data is output. The internally generated data input/output reference signal output can be disabled on each integrated circuit in response to a control signal, thus allowing a single one of the plurality of integrated circuits to be selected to generate the reference signal.
