Abstract

A static RAM having first word lines each defined by extended gate electrodes of MISFETs constituting memory cells, and second word lines which are separate from the first word lines. The RAM has a wiring for supplying a fixed potential such as a ground potential to the memory cells, the wiring being formed from the same layer as that for forming the second word lines.
