Abstract
The arrangement relates to bit lines which are widened to form contact surfaces (11, 21, 31, 41, 51) at the contacts (10, 20, 30, 40, 50) to underlying cells, the contacts being arranged in an at least a three-fold stagger. A minimum space requirement is achieved in conjunction with increased reliability when the distance b.sub.Sp between edges of adjacent bit lines has the same value everywhere, and the contact surfaces can thereby be enlarged.
