<p>PURPOSE:To improve a high speed of a reading operation. CONSTITUTION:An inverting amplifier 101 switches a switching transistor Q2 in response to a potential of a digit line to vary a voltage of a node SC. The node SC receives a current not only from a load transistor Q3 but also from a charging transistor Q1. Since a gate of the transistor Q1 is connected to a power source CC, a current driving capacity is high and a high speed of a reading operation is improved.</p> |
