Abstract: A control circuit including a storage circuit, a register, and a write protection logic circuit is provided. The storage circuit stores data, an enable-set value and a mode-set value. The register stores a protection-set value. The write protection logic circuit determines whether to change at least one of the enable-set value, the mode-set value, and the protection-set value according to the mode-set value after receiving a write command. In response to the mode-set value matching a pre-determined value, the write protection logic circuit changes at least one of the enable-set value, the mode-set value, and the protection-set value according to the protection-set value. In response to the mode-set value not matching the pre-determined value, the write protection logic circuit does not change the enable-set value and the mode-set value.
