Semiconductor memory with wordline control - generates wordline control signal for transfer to selected wordline and determines whether generated wordline signal should be boosted

摘要

A word line control signal generator (511) provides a signal to be transmitted to selected word line. A detector (701) responds to a different signal and determines wether a generated word line control signal should be boosted. A boosting circuit (702) responds to the detector for this purpose. Pref. the detector checks the voltage supply level to the semiconductor memory. A decision device responds accordingly to prevent the word line control signal boosting when the voltage level has exceeded a preset level. USE/ADVANTAGE - For dynamic semiconductor memories. Prevents unnecessary holding of wordline at high voltage, thus breakthrough voltage of wordline is not degraded.
