Claim Text:
1. A programming voltage generator for a nonvolatile memory device, comprising: a power circuit, for outputting a programming voltage according to a voltage control signal; a detector, for detecting 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; a switching circuit, for temporally dropping the programming voltage according to the indication signal; a control signal generator, for generating a plurality of regulation control signals; and a regulation circuit, for generating the voltage control signal according to the programming voltage and the regulation control signals; wherein the regulation circuit comprises: a programmable voltage divider, for generating a divided voltage according to the programming voltage and the regulation control signals; and a comparator, for comparing the divided voltage and a reference voltage to output the voltage control signal.
