PURPOSE:To raise quickly the first output with a light load, by using a capacitor of a large capacity to boost sufficiently and making the rise of the potential quick. CONSTITUTION:The potential of an output line l rises to Vcc by turn-on of a transistor TR Q3 and turn-off of a TR Q4 due to signals S1 and S2. While a word push (WP) signal is L-level, a capacitor C is connected between the output line l and the ground, and becomes a load of output TRs Q3 and Q4. For the purpose of showing a sufficient effect, the capacitor C is required to have a large capacity approximately equal to or more than the parasitic capacity of the signal line and a word line W, and thus, this load becomes large. |
