Abstract:
1. A high voltage generation circuit generating a high voltage output (VPP), comprising: a first node receiving an driving signal defined by a power source voltage (VCC); a first boosting unit connected between the first node and a second node, wherein the first boosting unit changes the electrical potential of the first node in response to the driving signal, and pre-charges the second node with a pre-charge voltage (VPP a second boosting unit connected between a third node and a fourth node, wherein the second boosting unit changes the electrical potential of the third node in response to the driving signal, and pre-charges the fourth node with the pre-charge voltage (VPP a delay circuit connected between first and third nodes and delaying an output from the first boosting unit to the second boosting unit; a pre-charge circuit pre-charging the second and fourth nodes with the pre-charge voltage (VPP a first switch response to a transfer signal connecting the second and fourth nodes; and a second switch response to a transmission signal outputting the high voltage output (VPP) from the fourth node.
