Abstract

Techniques for fast ramp, low supply charge-pump circuits are described herein. In an example embodiment, a non-volatile memory device comprises a flash memory array coupled to a fast charge-pump circuit. The charge-pump circuit comprises a first charge pump, an active charge pump coupled as input to the first charge pump, and a power supply coupled as input to the active charge pump. The active charge pump is configured to initialize the first charge pump to a greater absolute voltage than the power supply and to provide power to the first charge pump during an active mode of the flash memory array.
