Abstract
A bit line precharging circuit includes a first switch that connects a bit line to a first power source, a second switch that connects the bit line to a second power source whose voltage value is higher than voltage value of the first power source, and a control circuit including a delay element and configured to bring the second switch into conduction after a delay time by the delay element after bringing the first switch into conduction at the time of precharge of the bit line.
