Flash memory and associated programming method
A flash memory includes a program voltage generator, plural memory units, a current limiter, and a multi-bit program control unit. The program voltage generator is used for providing a constant program voltage during a detecting cycle and providing a dynamically-adjustable program voltage during a program cycle. The plural memory units output plural drain currents and plural data line voltages to plural data lines. The current limiter is used for receiving a reference current and a reference voltage, thereby controlling the plural drain currents. During the detecting cycle, a specified data line voltage of the plural data line voltages with the minimum voltage level is detected by the multi-bit program control unit. During the program cycle, the specified data line voltage is used as a feedback voltage, and the dynamically-adjustable program voltage is generated by the program voltage generator according to the feedback voltage.
