A programming operation is performed to write an original data into a first memory array in the memory device. The original data in the first memory array is verified, and whether to generate a write signal is determined according to a verification result. An error correction code is generated according to the original data, and the error correction code and a write address are stored temporarily in a buffer circuit of the memory device. When the write signal is generated, the error correction code and the write address in the buffer circuit are written into a second memory array in the memory device.
