Abstract:
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 first capacitor having a first end which is connected to the output node, and a second end which receives a first oscillation signal; a second transistor included in each boost unit; a second capacitor included in each boost unit and connected to said input portion thereof; and a third transistor connected to said output node, being unconnected to a gate of said first transistor, wherein both a drain and a gate of said second transistor are connected to said input portion, a source of said second transistor is connected to said output portion, and said gate of said first transistor is connected to the input portion of one of said boost units, and when said third transistor transfers a second voltage from a source of said third transistor to a drain of said third transistor said voltage generating/transferring circuit becomes disabled, and as long as said third transistor transfers said second voltage, said third transistor is on.
