ABSTRACT:
A word line driver incorporated in a semiconductor memory device is powered by an internal step-down voltage generator for energizing a selected word line, and an address transition detecting circuit causes an n-channel enhancement type switching transistor to temporally turn on between the address transition and completion of a charging operation on the selected word line, thereby preventing the internal step-down power voltage from undesirable decay.
