    • Provided is a bit line bridge detection method for selectively floating even-numbered or odd-numbered bit lines. The bit line bridge detection method simultaneously activates even-numbered sense amplifiers and odd-numbered sense amplifiers in response to a sense amplifier enable signal. The even-numbered sense amplifiers and the odd-numbered sense amplifiers are selectively disabled in response to a sense amplifier disable signal generated at a predetermined time after the sense amplifier enable signal is generated, and an even-numbered or odd-numbered sense amplifier selection signal which is stored in a mode register. As a result, the even-numbered bit lines and the odd-numbered bit lines are selectively floated. If data input to memory cells is inverted, a bit line bridge is detected.
