Abstract
A regulator for regulating a program voltage of a memory device is introduced. The regulator includes an operating amplifier, a program path emulation apparatus, and a current mirror coupled to the program path emulation apparatus and the operating amplifier. The current mirror is for controlling a current flowing in the program path emulation apparatus a multiple of a predetermined current. The program path emulation apparatus includes a bit line selection emulation unit for emulating a bit line selecting unit of the memory device, a path resistor for emulating a program path of a memory cell of the memory device, and a sector selection emulation unit for emulating a sector selecting unit of the memory device. The value of the predetermined current may be varied according to the program times of the memory cells of the memory device.
