Abstract
In a semiconductor memory device including a bit line precharge/equalizing circuit, the control system of the bit line precharge/equalizing circuit is changed in the normal operation mode and in the test mode. In the test mode, the bit line precharge/equalizing circuit is temporarily turned ON when an internal activation signal becomes non-active and then the bit line precharge/equalizing circuit is turned OFF after the potentials of paired bit lines are completely equalized.
