Abstract
An exemplary embodiment of the present disclosure provides a programming voltage generator for a nonvolatile memory device. The programming voltage generator comprises a power circuit, a detector, a switching circuit, a control signal generator, and a regulation circuit. The power circuit outputs a programming voltage according to a voltage control signal. The detector detects whether the programming voltage is larger than or equal to a breakdown voltage of the nonvolatile memory device, so as to output an indication signal. The switching circuit temporally drops the programming voltage according to the indication signal. The control signal generator generates a plurality of regulation control signals. The regulation circuit generates the voltage control signal according to the programming voltage and the regulation control signals.
