Abstract
An integrated circuit having a memory cell array and a method of forming an integrated circuit is disclosed. One embodiment provides bitlines running along a first direction, wordlines running along a second direction substantially perpendicular to the first direction, active areas and bitline contacts. The bitline contacts are arranged in columns extending in the second direction and in rows extending in the first direction. A distance between neighboring bitlines is DL, and a distance between neighboring bitline contacts is DC, DC being measured parallel to the first direction. The following relation holds: 1/2.25≦DL/DC≦1/1.75.
