PROBLEM TO BE SOLVED: To provide a sense amplifier capable of performing a stable data sensing operation.SOLUTION: The sense amplifier includes: inverter pairs, any one input terminal of which is connected to a bit line and the other one input terminal of which is connected a bit bar line; and a controller which precharges the bit line and the bit bar line to a level corresponding to an offset of the inverter pairs in response to a first control signal, and which senses a voltage difference of the bit line and the bit bar line using the inverter pairs by connecting output terminals of the inverter pairs to the bit line pairs in response to a second control signal. |
