US 10,650,866 B2 · Charge pump drive circuit

Abstract

A charge pump drive circuit is disclosed. The charge pump drive circuit includes a first pulse generating circuit and a second pulse generating circuit. Each of the first pulse generating circuit and the second pulse generating circuit is configured to connect to a charge pump. The first pulse generating circuit is configured to provide the charge pump with a series of first pulse signals. The second pulse generating circuit is configured to generate a second pulse signal in response to and based on an address translation detection signal and provide the second pulse signal to the charge pump or to the first pulse generating circuit. The first pulse generating circuit generates an additional first pulse signals based on the second pulse signal.
