A method for programming one or more memory cells is disclosed. The one or more memory cells need to be two sides operated. After verifying both sides of each memory cell to identify the sides of the memory cells to be programmed, a programming voltage pulse is given to the first sides of the memory cells identified to be programmed. Another verification process is performed for both sides of each memory cell to identify the sides of the memory cells to be programmed. Next, a programming voltage pulse is given to the second sides of the memory cells identified to be programmed. The verifying both sides, programming the first sides, verifying both sides, and programming the second sides will continue until the both sides of each memory cell are programmed to a target programming voltage. The target programming voltage might have multiple voltage levels.
