Abstract
A semiconductor memory device includes a memory cell array, a word line voltage generation circuit, a row decoder, a first switching circuit, and a second switching circuit. The first switching circuit is coupled to an output terminal of the word line voltage generation circuit, and supplies an external test voltage to the word line voltage output terminal. The second switching circuit is coupled between the first switching circuit and the word line voltage output terminal, and interrupts a current path from the word line voltage output terminal to the first switching circuit when a voltage level of the word line voltage output terminal is higher than that of a power supply voltage.
