A data split between a first data line and a second data line is caused to develop. At least one of the following sets of steps is performed: 1) a first power supply line of a sense amplifier is caused to rise towards a first power supply voltage value, and when the first power supply line reaches a first predetermined voltage value, the first power supply is caused to rise above the first power supply voltage value; and 2) a second power supply line of the sense amplifier is caused to fall towards a second power supply voltage value, and when the second power supply line reaches a second predetermined voltage value, the second power supply line is caused to fall below the second power supply voltage value. |
