A program circuit and method for a flash memory is provided. This invention utilizes a constant current to program the flash memory and modulate the threshold voltage of the flash memory. While a program circuit programming the flash memory, the present invention determines whether the threshold voltage reaches the anticipated value according to the variation of the drain voltage of the flash memory. Hence, the present invention can accurately modulate the threshold voltage of the programmed flash memory and shorten the programming time.
