Granted: 2003-04-11
Abstract: In a sense amplifier control circuit and method for a semiconductor memory device, a row address strobe (RAS) signal delay unit delays a RAS signal for a predetermined period of time. A sense amplifier control signal generator generates first and second sense amplifier control signals, responsive to the delayed RAS signal and a test mode control signal, which are enabled at the same time or at different periods depending on operation modes of the memory device. First and second sense amplifiers respectively sense and amplify the potential of odd-numbered and even-numbered bit line pairs of the memory device, responsive to the first and second sense amplifier control signals. The probability and accuracy of detecting bit line bridge defects are increased, because the times for sensing two adjacent bit lines are different.
