PURPOSE:To attain ease of high circuit integration and refresh operation by forming a selection signal having the relation of phase inverting. CONSTITUTION:A memory cell 68 connected to each of plural word lines, a row decoder 66 forming a selection signal commanding a prescribed number of word lines from plural word lines and a column decoder 70 applying selectively a different selection signal to a prescribed number of word lines base on the different two selection signals are provided. In this case, the two selection signals are formed in the timing phase-inverted mutually.
