Abstract

A memory cell 6 includes a M3 metal layer which incorporate continuous word lines 12 and power conductors formed of a plurality of separate power line sections 14 running parallel to the word lines. Interstitial gaps between the separate power line sections are larger in size than the power line sections themselves. The power line sections are disposed in a staggered arrangement either side of the word lines.
