ABSTRACT:
A circuit for generating word line control signals that have a stable boosting margin of the sub-word line driver: The circuit includes a first address buffer, a pre-decoder unit, a second address buffer, a main decoder and a circuit for generating a word-line boosting signal. The second address buffer delays a refresh count signal for a predetermined time and generates an enable signal having a predetermined pulse width in response to a row address setup signal and the delayed refresh count signal, and receives and latches a pre-decoded row address signals to output decoded row address signals in response to the enable signal. Accordingly, the circuit for generating word line control signals is capable of obtaining a stable self-boosting margin when the semiconductor memory device operates in a refresh mode.
