Abstract
An active region which forms two transistors included in a memory cell is arranged to have a strip shape along a predetermined axis crossing first and second bit lines at less than 90 degrees, whereby it is possible to reduce a junction area corresponding to a connection node of connecting the two transistors between the active region and a substrate and to reduce a leak current.
