A method for programming a memory array is provided. The memory array includes a memory cell string composed of a first transistor, a plurality of memory cells and a second transistor connected in series, and the method for programming the memory array includes following steps. In a setup phase, a switching memory cell in the memory cells is turned off, and a first voltage and a second voltage are applied to a first source/drain and a second source/drain of the switching memory cell. In a programming phase, a bit line connected to the memory cell string is floating, and a ramp signal is provided to a word line electrically connected to the switching memory cell.
