Abstract
A bit line sense amplifier overdriving method includes a step for reaching a bit line data signal to a full swing level by driving the sense amplifiers in accordance with an overdriving voltage in an overdriving pulse interval, when an overdriving pulse signal is generated at points in which the sense amplifiers are enabled and disabled in a data read operation and a data write operation. The method maintains a sufficiently long refresh interval during a refresh operation.
