Abstract
Bit lines (BL, BLR, BL, BLR, . . . ) of a ROM memory array with differential detection reading are arranged within two overlaid metallization levels so as to increase the read reliability of binary values stored in the array. The ROM array is divided into matrix segments (, . . . ) aligned parallel to the bit lines. The bit lines are shifted horizontally and/or vertically within transition regions (T) located between the segments of matrix, by effecting circular permutations between the positions of the bit lines that are divided up into groups of four.
