ABSTRACT:
In a semiconductor memory having word lines and power source lines such as bit lines, two word lines extending on both sides of each contact hole of one of the power source lines extending adjacent to each other extend between two adjacent contact holes of the other power source line, which are staggered from the contact hole of the one power source line. A peripheral circuit of the semiconductor memory can be simplified although the memory is suitable for high-speed operation and high integration.
