Abstract
With shrinking dimensions, and closely spaced runners, capacitive coupling between bitlines in dual port SRAMS becomes an important design issue. Techniques for reducing that coupling are described. A shielding runner placed between the read and write bitlines and tied to V.sub.DD or V.sub.SS substantially reduces unwanted crosstalk. Word lines can be similarly isolated.
