PCT No. PCT/JP93/01683 Sec. 371 Date Jun. 29, 1994 Sec. 102(e) Date Jun. 29, 1994 PCT Filed Nov. 17, 1993 PCT Pub. No. WO94/11943 PCT Pub. Date May 26, 1994.A booster power generating circuit according to the present invention comprises first to fourth booster circuits for supplying first to fourth booster potentials to first to fourth nodes in response to first to fourth pulse signals, a first precharge circuit for precharging the first node when controlled by the fourth booster potential from the fourth node, a second precharge circuit for precharging the third node when controlled by the second booster potential from the second node and a first output circuit for outputting the first booster potential of the first node to an output node, whereby a given booster potential can be output since there is no voltage drop of the boosted potential of the second and fourth nodes, there is obtained high potential between the first and third precharge circuits and the precharging speed of the first and third node is not slowed.
