ABSTRACT:
A boost voltage generator generates a boost voltage as a high-level voltage of word lines. First word decoders output a low-level voltage or the high-level voltage according to a first address signal in an active period, and outputs the high-level voltage in a standby period. A switch circuit connects a high-level voltage line for supplying the high-level voltage to the first word decoders, with a boost voltage line in the active period, and connects the same with an internal voltage line in the standby period. The internal voltage line is supplied with a voltage lower than the boost voltage. Word drivers supply the boost voltage to the word lines when the gates of their transistors receive the low-level voltage from the first word decoders, and output the low-level voltage to the word lines when the gates thereof receive the high-level voltage from the first word decoders.
