Abstract: A flash controller performs a data correction function while executing a copy back procedure for a flash memory, and the flash memory includes at least one memory unit and a page buffer. The flash controller contains: a transmission buffer, an error correction unit, a correction information register, and a microprocessor. The microprocessor reads out a data from, the page buffer and stores the data into the transmission buffer after producing a read instruction of page copy to the flash memory. The microprocessor controls the error correction unit to check and correct the data in the transmission buffer and calculate a check result. The microprocessor produces a different program command to record the corrected data into the memory unit according to the data error quantity of the check result. Thereby, the present invention can achieve the purpose of improving the flash controller in reliability and access efficiency.

Another characteristic of the present invention is that the negative voltage protecting diode located between the output/input bus and the grounding in the functional circuit is changed to a stable voltage Zener diode. Therefore, the high voltage static electricity is guided into the grounding via the Zener diode so that the goals of anti-static electricity and protecting the functional unit are achieved.
