Abstract
PURPOSE:To decrease the operation cycle of an RAM, by separating a bootstrap capacitance of large capacity from a common data line at the time of leading edge of a word control signal, and at the same time precharging it with other MISFET during boosting. CONSTITUTION:A MISFETT51 applying a power supply voltage vcc to the gate is provided between an output line of a pulse generating circuit phix-GENE provided on a common word line and a connecting point N1 in a booster circuit phix- BOOS, a bootstrap capacitance CB21 is given between connecting points N2, N1 to which a pulse signal phipad delayed for the leading time from the word line control signal phix, and an MISFETT52 the gate of which is a voltage of N1 is applied is provided between the output line and a connecting point N3 respectively. A CB22 between the N2 and N3 is precharged at the reference potential signal level period of the pulse signal at the N2 with a switching element T53 between the N3 and the power supply voltage Vcc. Thus, since the CB22 of comparatively large capacity is separated from the common data line at the time of leading edge of the phix, the leading speed of the phix is quickened and the operation cycle of an RAM is shortened.
