PURPOSE: To reduce noise interference by making complimentary bit lines intersect each other, and decreasing the differential effect of undesirable signals induced therein. CONSTITUTION: A pair of complimentary bit lines 26 and 28 intersects each other at a point 46 so that one section of the bit line 26 is adjacent to a data bus conductor 24, and one section of the bit line 28 is also adjacent to the conductor 24. Therefore, an undesirable signal entering the upper bit line section 26 due to parasitic capacity 38 has a same intensity as an undesirable signal entering the upper section of bit line 28 due to parasitic capacity 40. Similarly, parasitic capacities 42 and 44 connect voltages of a same intensity to each lower section of the bit lines 26 and 28 respectively. And the intersected bit lines 26 and 28 induce undesirable signals in both bit lines 26 and 28 and reduces the differential effect. Thus, noise interference in memory is reduced. |
