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.

A method of reducing power consumption caused by leakage current in an interface circuit between modules that are driven by different power sources is disclosed. The interface circuit includes an output driver that operates by a first power supply voltage in a first mode and does not operate in a second mode in which the first power supply voltage is prevented from being applied, an input buffer that is operated by a second power supply voltage in the first and second modes, and a transmission line that connects an output terminal of the output driver to an input terminal of the input buffer. The interface circuit further includes a current leakage prevention circuit that prevents, in the second mode, a current leakage in the input buffer between a second power supply voltage source that supplies the second power supply voltage and a ground voltage source.
