Abstract: A tiltless OIS circuit includes a first signal processing unit generating a first direction-position detection signal and a tilt detection signal based on a first direction-first sensing signal and a first direction-second sensing signal, a control unit generating a first direction position control signal, a tilt control signal, and a second direction position control signal, based on the first direction-position detection signal, the tilt detection signal, and a second direction sensing signal, respectively, a second signal processing unit generating a first direction-first position control signal and a first direction-second position control signal based on the first direction position control signal and the tilt control signal, and a driving unit generating a first direction-first driving signal, a first direction-second driving signal, and a second direction driving signal, based on the first direction-first position control signal, the first direction-second position control signal, and the second direct

Abstract: A method for maintaining a stable input/output line precharging and equalizing level and performing fast data access during active cycle of a row address strobe signal. In the inventive semiconductor memory device reading out through bit lines information stored in a memory cells, producing the read out information through a selected column line, and precharging or equalizing the input/output lines to a predetermined level by using a first and second precharging circuits connected between the input/output lines, a first precharging signal in accordance with a address for selecting a word line is supplied to the first precharging circuit, during a time interval before the address signal is applied to the first precharging circuit.
