A semiconductor memory device may include a semiconductor substrate having a plurality of active regions wherein each active region has a length in a direction of a first axis and a width in a direction of a second axis. The length may be greater than the width, and the plurality of active regions may be provided in a plurality of columns in the direction of the second axis. A plurality of wordline pairs may be provided on the substrate, with each wordline pair crossing active regions of a respective column of active regions defining a drain portion of each active region between wordlines of the respective wordline pair. A plurality of bitlines on the substrate may cross the plurality of wordline pairs, with each bitline being electrically coupled to a drain portion of a respective active region of each column, and with each bitline crossing drain portions of active regions of adjacent columns in different directions so that different portions of a same bitline are aligned in different directions on different active regions of adjacent columns.
