Abstract

A multi-mode voltage pump may be configured to select an operational mode based on a temperature of a semiconductor device. The selected mode for a range of temperature values may be determined based on process variations and operational differences caused by temperature changes. The different selected modes of operation of the multi-mode voltage pump may provide pumped voltage having different voltage magnitudes. For example, the multi-mode voltage pump may operate in a first mode that uses two stages to provide a first VPP voltage, a second mode that uses a single stage to provide a second VPP voltage, or a third mode that uses a mixture of a single stage and two stages to provide a third VPP voltage. The third VPP voltage may be between the first and second VPP voltages, with the first VPP voltage having the greatest magnitude. Control signal timing of circuitry of the multi-mode voltage pump may be based on an oscillator signal.
