Abstract

What is disclosed is a novel memory array and process for creating a memory array to reduce wireline variability. The method includes accessing a routing design of a memory array with a plurality of memory cells. Each memory cell in the array includes one or more access devices, and a group of wires electrically connected between one or more of the memory cells and peripheral circuitry (PC). The group of the group of wires is divided into at least one subgroup (N). Next, a capacitance (C1, C2 . . . CN) of each wire in the subgroup (N) is calculated. Continuing further, a maximum capacitance (CMAX) of wires in the subgroup (N) is determined. An add-on capacitance to be added to a number (NA) of the wires in the subgroup (N) is calculated.
