ABSTRACT:
An address input buffer in a semiconductor memory device. The address buffer has a differential amplifying device for differentially amplifying a reference voltage and an external address signal, and a controlling device for generating a bias control signal by receiving a refresh signal and a bank active signal to control the differential amplifying device. Activation of the bias control signal depends on the bank active signal when the refresh signal is abnormally activated in an initialization process.
