Abstract
Embodiments of the present invention provide a memory array of dual part cells and design structure thereof. The memory array has a pair of twisted write bit lines and a pair of twisted read bit lines for each column. The twist is made by alternating the vertical position of each bit line pair in each section of a column, with the result of generating common mode nose and of reducing differential mode noise.
