Non-volatile memory device and charge pump circuit for the same

摘要

A charge pump apparatus comprises a plurality of charge pump stages. The charge pump stages each include a respective output node. Output nodes are connected to charge boosting circuitry and to precharge circuitry. The charge boosting circuit receives one or more clock signals. The precharge circuits have a first state allowing the respective pump-stage output node to fluctuate at a level above a standby wordline voltage, and a second state coupling the respective pump-stage output node to the standby wordline voltage.
