PROBLEM TO BE SOLVED: To provide a two phase pre-charge circuit coping with quality request for a low power DRAM element and a cancel circuit for current at the time of standby of short circuit of a DRAM element constituted by combining the circuits. SOLUTION: A two phase pre-charge circuit is operated so that voltage by a pre-charge voltage source is applied to bit lines in an operation mode period, but the circuit is turned to be in an off-state in a standby mode period. Therefore, a current when standby caused by short circuit of a bit line and a word line is cancelled. COPYRIGHT: (C)2004,JPO
