It's not a bug, it's a random feature.
There's no problem, only learning opportunities.
I have just solve the problem. I connect a capacitor between 5V and GND of 7805. Then I can answer my own question)
During write operation, 7805 cannot handle the voltage changes itself. So a write error occurs. A capacitor solves the problem.
