International ClassG11C 007/00Foreign Application Priority Data1993-09-10 JPAbstractAn equalizing circuit is connected between a pair of bit lines. The equalizing circuit is made up of three MOS transistors and an equalization control signal is supplied to the gates of the MOS transistors. A sense amplifier circuit is connected to the bit lines. The sense amplifier circuit amplifies the potential difference occurring between the bit lines, for the detection of data. The equalization control signal is output from a level conversion circuit. An internal boosted voltage-generating circuit constantly generates a booted voltage which is higher than an externally-applied power supply voltage applied to a power supply terminal. The boosted voltage is applied to the level conversion circuit. The level conversion circuit converts an input control signal, whose high-level voltage is equal to, or lower than the externally-applied power supply voltage, into the boosted voltage, thereby generating the equalization control signal.Field of SearchPrechargeIncluding reference or bias voltage generator Data preservation Including level shift or pull-up circuit Including signal comparison Particular decoder or driver circuit POWERING Complementing/balancing Having stabilized bias or power supply level Charge pump details With field-effect transistor With bootstrap circuit | |
