<p>A variable stage charge pump for a flash memory device is described. The variable stage charge pump includes a first charge pump and a second charge pump. A first switch couples an output of the first charge pump to an input of the second charge pump. A second switch couples an input of the first charge pump to the input of the second charge pump. The first and second charge pumps are series-coupled to a common output node when the first switch is in a first position and the second switch is in a second position, wherein the first and second charge pumps are parallel-coupled to the common output node when the first switch is in the second position and the second switch is in the first position.</p> |
