Abstract
Following latching of a word line select signal by a latch circuit, a transfer gate is turned off. When a word line is selected, the voltage applied to the latch circuit is shifted to a desired level to apply a desired voltage to the word line from a word line driver. As a result, a predecode signal is applied to a small size buffering circuit to be transmitted to the word line driver at a potential level between Vcc-GND. Therefore, the parasitic capacitance accompanying a predecode signal is reduced.
