Abstract:
1. A voltage generating/transferring circuit comprising: a boost unit group including a plurality of boost units series-connected between input and output nodes, each boost unit having input and output portions; a first transistor connected between the input node and a node for receiving a first voltage; a second transistor included in each boost unit; a first capacitor included in each boost unit and connected to the input portion; and a third transistor connected to a first node, and being unconnected to a second node, wherein the first node is one of the output node and a gate of the first transistor and the second node is the other of the output node and the gate of the first transistor, wherein both a drain and a gate of the second transistor are connected to the input portion, a source of the second transistor is connected to the output portion, and the gate of the first transistor is connected to the input portion of one of the plurality of boost units, and wherein the voltage generating/transferring circuit becomes disabled when the third transistor transfers a second voltage from a source of the third transistor to a drain of the third transistor, and as long as the third transistor transfers the second voltage, the third transistor is on.
